Install Requirements script needs to be updated for libyang installation

Description

Libyang is Python library that needs to be installed according to the install_requirements.sh script. In the develop branch that I'm using, the script fails with the error: 'ERROR: Could not build wheels for libyang, which is required to install pyproject.toml-based projects'. I also attach the full log here: install_requirements.log

Now, the repo contains the fix of using the previous Libyang version of v2.1.148 (https://labs.etsi.org/rep/tfs/controller/-/blob/develop/install_requirements.sh#L35-36). However the git commands are executed outside of the cloned libyang folder. As a workaround, I locally added: 'cd libyang' before L35 and 'cd ..' after L36 so the rest of the script can proceed normally. There might be a cleaner fix.

It should be noted that the Dockerfile contains the folder change (https://labs.etsi.org/rep/tfs/controller/-/blob/develop/src/nbi/Dockerfile#L64-66), so nothings needs to be changed there. Only the install_requirements.sh script needs the said update.
