Adapt asttokens for astroid 4.x

[eendebakpt]

• Replace deprecated usage of astroid.Const with astroid.nodes.Const
• Add manager argument to AstroidBuilder since the default argument was removed on astroid 4.x
• Adapt the tests to treat astroid v4 in the same way as v3

Fixes #164

Thank you! I added a commit to silence an error in mypy related to astroid typings; with that, all tests passed. It would make sense to add astroid 4 into the mix of what's getting tested -- I don't think it's included yet.

maybe setup.cfg needs update too?

I created #166

Thanks for the code change, test and merge.
However, pypi.org still contains asttokens 3.0.0 from Nov 2024 as latest version.
Could you bump the latest change to pypi?

[eendebakpt]

@dsagal A new release would be nice. I created #167 to add 3.14 to the CI and remove 3.8.

[welldone43]

A new release would be really great.
By now asttokens has 2..3 million downloads per day from pypi. Pytest depends on it.

I pushed a new release. Special thank you to @eendebakpt for the needed maintenance!
