updated release-howto.md

[tobixen]

Another thing, the RELEASE-HOWTO.md probably needs some modifications (after several really silly embarrassing mistakes while releasing, I've made a rather complicated procedure to make sure I'm on the correct branch, that the version number is updated, that the tag is correct and that I'm doing the dist from a clean checkout - I suppose some of the steps may be sidestepped now).

Seems like my last comment was posted some seconds too late :-)

[tobixen]

Or maybe not. There are still some steps in the RELEASE-HOWTO that doesn't make sense now I think (like grepping for the version number from __init__.py)

[sim0nx]

I removed those obsolete parts. Should hopefully be fine now :-)

>>> import caldav
>>> caldav.__version__
'1.3.10.dev4+g70e7856.d20231219'

lovely :-)
