More strict handling of requirement specifiers in requirements.txt.

[garrettgu10]

After some discussion, the runtime team has decided that we should prevent users from specifying version identifiers altogether within requirements.txt, rather than silently dropping them. This would prevent users from being deluded into thinking that they could specify versions of Python packages in Python workers, then being confused because their code mysteriously breaks.

Fixes EW-8189.
