CI: Switch to action-gh-release.

[Gadgetoid]

Switch from the long deprecated upload-release-asset to action-gh-release and attempt to replicate the same behaviour.

Avoids nodejs and set-output deprecation warnings:

• https://github.blog/changelog/2023-06-13-github-actions-all-actions-will-run-on-node16-instead-of-node12-by-default/
• https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/

I've put this off for too long! upload-release-asset has been deprecated and unmaintained for years, causing a growing number of warnings in the Actions output.

Test release: https://github.com/32blit/32blit-sdk/releases/tag/TEST-DO-NOT-EAT

No warnings, less code and it works... seems like a win. (Was also avoiding this when updating actions)

[Gadgetoid]

Will merge and hope it doesn't cause us a headache for the next release!

There should probably be a release soon. You've been busy 😆 https://github.com/32blit/32blit-sdk/compare/v0.3.2...master

Mmm, haven't even merged any of the big stuff yet... and now I have a bunch of fixes from working on a HSTX driver. :thinking:

Oooooooooo!

To be fair, a release of miscellaneous bugfixes probably isn't a bad thing to do before the big stuff!
