python: add 3.10 - 3.15 to the version search list

Fixes automake bug https://bugs.gnu.org/53530.

Based on the cadence of Automake releases, add the current Python
release (3.10), the current Python development (3.11), and then 4
more versions on top of that.  It doesn't hurt to check for a few
extra versions here since this is the fallback logic when the main
`python` and `python3` programs aren't found.

* m4/python.m4: Add python3.10 - python3.15.
* NEWS: Mention new Python versions.
