[backport] cherry-pick slice-syntax fix for 0.920

[Zac-HD]

This PR cherrypicks #11345 onto the 0.920 release branch, as requested by @ilevkivskyi in #11158 (comment).

[Zac-HD]

Looks like this is failing with an unrelated pip install error?

Yeah we should also probably cherry pick #11356

[ilevkivskyi]

OK, I can cp that.

Btw there is also another failure

  main:3: error: syntax error in type comment   (diff)
Actual:
  main:2: error: Module "typing" has no attribute "Dict" (diff)
  main:2: note: Maybe your test fixture does not define "builtins.dict"? (diff)
  main:2: note: Consider adding [builtins fixtures/dict.pyi] to your test description (diff)

[ilevkivskyi]

I just cherry-picked that commit.

[Zac-HD]

Ah, that was related to #11241 I think, which this cherrypick skipped over.

[ilevkivskyi]

Btw does anyone know why we don't run tests on the release branch itself? (I see no green checkmarks on CPs here https://github.com/python/mypy/commits/release-0.920)
