Setup automated changelog generation for release process

[dhomeier]

Description

Adding workflow and configuration for updating changelog automatically from PR titles and labels, using GH actions.

The next release action would thus create entries for these PRs (+ any to come until then), to be verified:

- Update API to support `echo>=0.6` and `vispy=0.11`. [#373]

Labels for documentation, no-changelog-entry-needed (+skip-changelog) have yet to be added. Detailed instructions are linking to http://docs.glueviz.org/en/stable/developer_guide/release.html, which will become live after the next glue-core release.

Oh well, something new again in vispy 0.11.1dev – but at least 3D scatter still seems to work on macOS 12.6 (although I cannot reproduce the test failure on my Rosetta system either). The Linux dev job obviously needs to be moved to Python 3.8+ (perhaps discontinue 3.7 support here as well?). And Windows appears to have no functional PyQt5 for 3.10:

Can not process PyQt5==5.14 from https://files.pythonhosted.org/packages/7c/5b/e760ec4f868cb77cee45b4554bf15d3fe6972176e89c4e3faac941213694/PyQt5-5.14.0.tar.gz This package has an invalid build-system.requires key in pyproject.toml. It contains an invalid requirement: 'sip >=5.0.1 <6'

Windows tests seem to crash with the access violation exception as soon as any Vispy3DViewer is added to the GlueApplication; to be investigated further...
