action(post-release): use fetch-depth, quoting and fix git commands

[v1v]

depth is not a valid argument... :/

Set fetch-depth: 0 to fetch all history for all branches and tag

In addition I fixed some quoting and git commands

Test

This build is the one testing the post-release steps. 👼 for not testing this earlier :/

v1v#40 was created automatically (i used some cosmetic changes to validate this)

Eek! Good catch!
