chore: bump version to 1.5.0.0

Shipping the playlist season grouping feature under 1.4.4.0 would mean
two materially different binaries sharing a version string, which makes
"which build are you running?" unanswerable. A minor bump reflects the
new feature and the two bug fixes.

Version is kept in sync by hand across Directory.Build.props and
build.yaml. The release workflow derives its own version from the git
tag, so it needs no change.

The plugin GUID is deliberately unchanged. This fork is an update to the
original plugin, not a parallel install: Jellyfin identifies plugins by
GUID, so a new one would present as a second plugin, abandon the
existing configuration, re-run the one time Season fetcher migration,
and break upgrades from upstream. The GUID also has no bearing on cached
library data, which is keyed by item id and by the provider name string.
