CI: Temporarily skip paths with spaces to avoid error

[hugovk]

PRs like these:

• gh-105071: add PyUnstable_Exc_PrepReraiseStar to expose except* implementation in the unstable API #105072
• gh-105107: Remove PyEval_CallFunction() function #105108

Have NEWS files in subdirectories containing spaces:

• Misc/NEWS.d/next/C API/2023-05-30-10-15-13.gh-issue-105071.dPtp7c.rst
• Misc/NEWS.d/next/C API/2023-05-30-19-11-09.gh-issue-105107.YQwMnm.rst

But the https://github.com/Ana06/get-changed-files action (added in #103914) fails for such files with:

Error: One of your files includes a space. Consider using a different output format or removing spaces from your filenames. Please submit an issue on this action's GitHub repo.

We ran into this before and worked around it in #103019 by skipping Misc and its subdirs.

Let's do something similar here, by replacing Misc with a list of its subdirs that are absent a space.

See also python/core-workflow#186 to rename the C API and Core and Builtins directories to C-API and Core-and-Builtins to avoid this altogether.

✅ No error with a dummy file at Misc/NEWS.d/next/C API/2023-05-30-21-34-29.gh-issue-105107.1mmbfA.rst (05cd028):

But the https://github.com/Ana06/get-changed-files action (added in #103914) fails for such files with

Maybe you should report the bug there?

[hugovk]

It's a feature: https://github.com/Ana06/get-changed-files#usage says the default behaviour is to return files separated by spaces (format: 'space-delimited'), and will fail if any files contain spaces. They suggest using one of the other formats in such case (CSV, JSON).

(Let's continue discussion in #103914).

@vstinner I've just submitted a proper fix: #105151
