Add Generic.EmphStrong token

[diskdance]

Note that some theme do not use bold or italic styling for Generic.Emph or Generic.Strong token. For these themes, I didn't touch them.

Tested to work on default theme.

Closes #2307.

@jeanas Is there an easy way to allow failures on -dev Python variants to fail gracefully? This seems completely unrelated/a Python 3.12 specific issue which we can't solve from our end?

[jeanas]

3.12 was introduced by @hugovk in #2324.

I won't have a computer with Git this afternoon and probably tomorrow, but if I read actions/runner#2347 correctly, we should set continue-on-error on the 3.12 job, and just ignore the red CI checkmark when it's the only failed job.

(GitLab does better than GitHub here.)

[hugovk]

The -W error is converting a deprecation warning into an error.

This change will allow the other jobs to continue, even if 3.12 is failing:

Please see #2445 for that.

The deprecation warning is:

DeprecationWarning: ast.Str is deprecated and will be removed in Python 3.14; use ast.Constant instead

Out of scope for this PR, but let's find where that is coming from and either fix it or temporarily silence it. To unblock this PR we could temporarily remove -W error for 3.12, or even comment out 3.12 from the CI.

The warning could be coming from pytest, I know they're fixing some of those and should have a fix after the next 3.12 beta: pytest-dev/pytest#10894 (comment)

And the next beta is scheduled for Tuesday: https://peps.python.org/pep-0693/

[hugovk]

Confirming the deprecation warning comes from ast.Str in pytest:

• https://github.com/pytest-dev/pytest/blob/29d16d293965a9dc3511576113db8f9eff2c8bc1/src/_pytest/assertion/rewrite.py#L683

I've updated PR #2445 to temporarily skip warnings for 3.12 on the CI until pytest-dev/pytest#10894 is fixed.

@diskdance Please rebase this on master, it should fix the failures.

Thanks!
