Also release in the Trigger Release workflow

The first implementation of the trigger-release would not push a tag,
meaning that the Release workflow was not getting triggered. While we
could have changed the Release workflow to react on "Trigger Release"
workflow runs, the inter-dependency felt awkward and brittle:

    diff --git a/.github/workflows/release.yml b/.github/workflows/release.yml
    index b711c5cf..843fdb70 100644
    --- a/.github/workflows/release.yml
    +++ b/.github/workflows/release.yml

Instead of doing the above, introducing duplication between "Trigger
Release" and "Release" seemed simpler from a cognitive perspective. Now,
releases are produced via the Release workflow when tags are pushed, and
also when releases are triggered via "Trigger Release", now renamed to
"Auto Release".
