minor clarifications in helm deployment guide

In folder `kubernetes/helm/openslice/files/org.etsi.osl.portal.web/src/js` you must make a copy of `config.js.default` file and rename it to `config.js`. 

```bash

# Starting from the root project directory

cd kubernetes/helm/openslice/files/org.etsi.osl.portal.web/src/js

```

```bash

cp config.js.default config.js

```

This is **mandatory** for the configuration file to be discoverable.

Edit the `config.js` configuration file with your static configuration, if needed.

```js

{

  TITLE: "OpenSlice by ETSI",

  WIKI: "https://osl.etsi.org/documentation/",

  BUGZILLA: "{{ .Values.rooturl }}/bugzilla",

  STATUS: "{{ .Values.rooturl }}/status",

  APIURL: "{{ .Values.rooturl }}",

  WEBURL: "{{ .Values.rooturl }}/nfvportal",

  APIOAUTHURL: "{{ .Values.rooturl }}/auth/realms/openslice",

  APITMFURL: "{{ .Values.rooturl }}/tmf-api/serviceCatalogManagement/v4"

}

```

### TMF Web UI

cd kubernetes/helm/openslice/files/org.etsi.osl.tmf.web/src/assets/config

```

E.g. You may edit "TITLE", "WIKI", etc properties with your domain title. Also configure TMF's API and Keycloak's location for the web application, if needed.

```json

{	      

    "TITLE": "OpenSlice by ETSI",

    "PORTALVERSION":"{{{ documentation_version }}}",

    "WIKI": "https://osl.etsi.org/documentation",

    "BUGZILLA": "{BASEURL}/bugzilla/",

    "STATUS": "{BASEURL}/status/",

    "WEBURL": "{BASEURL}",

    "PORTAL_REPO_APIURL": "{BASEURL}/osapi",

    "ASSURANCE_SERVICE_MGMT_APIURL": "{BASEURL}/oas-api",

    "APITMFURL": "{BASEURL}/tmf-api",

    "OAUTH_CONFIG" : {

        "issuer": "{BASEURL}/auth/realms/openslice",

        "loginUrl": "{BASEURL}/auth/realms/openslice/protocol/openid-connect/auth",

        "tokenEndpoint": "{BASEURL}/auth/realms/openslice/protocol/openid-connect/token",

        "userinfoEndpoint": "{BASEURL}/auth/realms/openslice/protocol/openid-connect/userinfo",

        "redirectUri": "{BASEURL}/redirect",

        "logoutUrl": "{BASEURL}/auth/realms/openslice/protocol/openid-connect/logout", 

        "postLogoutRedirectUri": "{BASEURL}",

        "responseType": "code",

        "oidc": false,

        "clientId": "osapiWebClientId",

        "dummyClientSecret": "secret",

        "requireHttps": false,

        "useHttpBasicAuth": true,

        "clearHashAfterLogin": false,

        "showDebugInformation": true

    }

}

```bash

cp config.prod.default.json config.prod.json

cp theming.default.scss theming.scss

```

> The {BASEURL} placeholder in the file automatically detects the Origin (Protocol://Domain:Port) of the deployment and applies it to every respective property. E.g. If you are attempting a local deployment of OpenSlice, then {BASEURL} is automatically translated to "http://localhost". Similarly, you may use {BASEURL} to translate to a public deployment configuration, e.g. "https://portal.openslice.eu".

If further customization, apart from the default provided, is needed for branding (Logo, Footer) then `config.theming.json` needs to be created in kubernetes/helm/openslice/files/org.etsi.osl.tmf.web/src/assets/config directory, as follows:

E.g. You may edit the `config.prod.json`, changing "TITLE", "WIKI", etc properties with your domain title. Also configure TMF's API and Keycloak's location for the web application, if needed.
