Update to Node 20

The JS world keeps dragging people through updates that we don’t ask for.

v1.1

Adds tag filtering and ability to obtain raw git tag name

The first release always looked at the most recent tag, which would be fine as long as the only things you ever tagged were maven versions. But sometimes you want to use tags for other things, so this version scans all the tags on the current branch, in reverse chronological order, until it finds one that appears to name a maven version.

It can also optionally export a second environment variable with the actual git tag name that was selected.

Use latest actions core and exec

The mechanism being used to save state and set output values has been deprecated.

Update to Node 16

GitLab has deprecated the version of Node that this tag had been using.

1.1.5

Fix broken build, oops.

1.1.4

Try removing stale, vestigial dist directory.

1.1.3

Update to new core library to replace deprecated mechanism for setting environment variables.

v1.0

First published release, with corrected format for version tag.
