chore(release): raise the version line above 1.1.0-beta.1 (decidesk) (#932)

The App Store serves 1.1.0-beta.1 (decidesk) for this app, and the release workflow
was computing a beta BELOW it. The baseline comes from this repo's latest
stable tag and appinfo/info.xml, neither of which knows what was published
while the fleet released from Codeberg -- that line had walked up a minor
that only exists as prerelease tags, which the stable-tag filter cannot see.

The store has no version ordering rule (_check_permission validates
existence and ownership only), so a lower version uploads with a 200 and
is then never offered to anyone already on the higher one.

Setting the baseline to 1.1.0 makes the next beta 1.1.1-beta.<ts>,
which clears it. Minor bump only -- the major is unchanged.
