Update bootstrap gen

[owais]

Description

Global generate check was removed from CI workflow and a specific check was added to generate bootstrap script in this commit:
d2984f5#diff-faff1af3d8ff408964a57b2e475f69a6b7c7b71c9978cccc8f471798caac2c88L112-L114
d2984f5#diff-0b911e478cf36c1398ccb7c6b5a371bc2fb5b7a962f897ae28acd3027fe1cecdR109-R120

However, it prevented the checks to actually run for code generation scripts other than genertate_instrumentation_bootstrap.py. At this point we had generate check only working for generate_instrumentation_bootstrap.py in CI.

Next change was migration of opentelemetry-instrumentation to contrib which included removal of the bootstap specific check here: 7cf3cb4#diff-0b911e478cf36c1398ccb7c6b5a371bc2fb5b7a962f897ae28acd3027fe1cecdL109-L120

Since that commit, we haven't had generate checks run in CI for any script.

This PR adds the generate checks back.

As a direct result of this, our latest release is somewhat broken. Installing opentelemetry-instrumentation==0.25b1 install a bootstrap command which forces a downgrade to 0.25b0 of all instrumentation packages.

Effect

Check is working as expected now:
