Fix compilation inside tgi (#700)

* refactor(tgi): do not require TGI_VERSION

Since bumping the TGI version always require adapting the Dockerfile
it is useless to have it defined outside of the Dockerfile.

* fix(tgi): silent build warnings

* fix(tgi): add missing libxml2 package

This package is required by the neuronx compiler, but not pulled
automatically.
