Update dependency for typed-ast

[deantvv]

typed-ast has an issue which will lead to error: undefined symbol _PyUnicode_DecodeUnicodeEscape

They fix this error in 1.5.0, so here comes the update.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe) and found it was in an excellent condition.

@carlodri Could you take a look at this?

Hi @deantvv, thanks for the PR. Not sure how to deal with this properly, since the error seems to occur only with Python 3.9.8, and black should depend on typet-ast only for Python < 3.8. This is because the recipe has been made noarch. The proper way should be remove the noarch and constrain the typed-ast as appropriate, but that has a resource cost (CI particularly). @conda-forge/black what do yo think?

@carlodri I only understood that the error only occurs with Python 3.9.8 and typed-ast 1.4.x after you mentioned it.
Since Python 3.9.8 is not available on both conda and conda-forge channels, and typed-ast isn't needed after Python > 3.8. It seems this PR is unnecessary. But there is still cases when people (like me) maintain a local conda channel, that still provide Python 3.9.8 and when the solver use that unfortunate combination (python=3.9.8, typed-ast=1.4.*, black), people will scratch their head for several minutes only to find the fix is conda install typed-ast=1.5. IMO, since typed-ast make a new release for this fix, it's worth it for black to bump dependency.
I also agree with you to drop the noarch: python part, instead of fixing this stuff. Since there is several packages that aren't needed for newer version of python like dataclasses, typed-ast, typing_extensions and also tomli.
Anyway, thanks for the quick respond and the reasoning for not update them. 🙏🙏
