Add action to test with upstream linkml v2

[sneakers-the-rat]

Continues: https://github.com/linkml/linkml-runtime/pull/316

Sorry to keep doing this with CI actions - as far as I know I can't test them on the fork until they are in main?

The previous action wouldn't run because the dynamic versioning plugin can't detect version when run within a poetry shell - https://github.com/mtkennerly/poetry-dynamic-versioning?tab=readme-ov-file#caveats

you also apparently need to explicitly install the plugin.

so i modified it so that we create an arbitrarily high version with the commit hash appended to it so we can be sure that the current version is being installed rather than a cached version.

You can see that the action is running *but correctly failing due to https://github.com/linkml/linkml/issues/2047 * here - https://github.com/sneakers-the-rat/linkml-runtime/actions/runs/8531972641/job/23372442173

this should get squash merged, but wanted to preserve commit history in PR so it's possible to see the various options i tried. blah. one day this will all be done and our CI will be spic and span

Thinking about what we need for PRs like https://github.com/linkml/linkml-runtime/pull/314 - thats a change that also requires a change in upstream to pass ( https://github.com/linkml/linkml/pull/2032 ). Is it possible/should we add some input arguments that allow this to be run against a specific version of upstream? Like I know we can add arguments, but is there a way to make that sorta streamlined - like in the OP I put some line that links to the branch of upstream to test against.

The manual version would just be putting in username, repo name and branch, with defaults for all three, which is not too bad.

Im p sure the most recent changes to the action are better than this lol
