Do not fail on invalid extracted requirements

[AyanSinhaMahapatra]

We were getting pipeline failures on wrongly parsed extracted requirements in someplaces:

'npm:wrap-ansi@^7.0.0' is not a valid <class 'univers.versions.SemverVersion'>

Traceback:

• We should not fail the entire pipeline here, we were already catching InvalidVersionRange exceptions, but we also need to catch InvalidVersion exceptions here
• Also adding project errors on invalid versions/version ranges as these can be package manifest parsing bugs.
