.github/zephyr: switch to python 3.10 on windows

[LaurentiuM1234]

Zephyr commit b3b8360f3993 ("west: runners: Add west rtt command with pyocd implementation") adds some functionality to the west commands making use of the pipe ("|") operator for function return type hinting. As per PEP 604 1, this operator can be used for writing union types starting from python 3.10. Since the SOF windows builds use python 3.8 this leads to the CI failing.

To fix this, switch to using python 3.10. This is not a problem for Linux CI jobs as they already use python 3.10.

The following is a snippet of a failed windows CI job regarding this:

File "D:\a\sof\sof\workspace\zephyr\scripts/west_commands\runners\core.py", line 780, in ZephyrBinaryRunner

def get_rtt_address(self) -> int | None:

TypeError: unsupported operand type(s) for |: 'type' and 'NoneType'

No breakage so far on the windows build jobs run on this PR.

I'm a bit concerned about https://sof-ci.01.org/sofpr/PR9469/build7967/build/firmware_community/tgl.log from #9469.

@marc-hb does the Intel CI build job use a different, internal workflow script which still uses an older python version? It seems like it still continues to use python 3.8.

Also, the PR exposing this issue is #9372, which does a Zephyr hash bump. The failing windows CI build job logs can be found there.

Unfortunately yes. This is tracked in internal issues 351 and 606

Maybe there is a somewhat equivalent way to do this in 3.8? This could buy a little bit of time...

My 2 cents.
