build: remove axe checks from e2e tests (#26980)

Removes the code for running Axe against the e2e tests since it wasn't catching many failures. Automated accessibility checks have been set up in g3 which should be a bit closer to what we're looking for during GAR.

(cherry picked from commit 22e928c)
