Prepare release

[yguclu]

Make the necessary changes for being able to upload the psydac package to PyPI through a CI workflow:

• Add actions ubuntu_install and macos_install for installation of non-Python dependencies
• Require Python >= 3.10 (3.9 is no longer supported). Run tests with Python 3.14, too
• Require Pyccel >= 2.1.0 and use its new subcommands
• Update PETSc version to 3.24.2
• Add igakit as a git submodule
• Use meson-python as build backend to bundle igakit into psydac for publishing to PyPI
• Remove setup.py after dropping setuptools build backend
• Write PSYDAC in all caps across the whole repository
• Avoid version duplication: have psydac/version.py read value from pyproject.toml
• Update instructions for editable install: flag --no-build-isolation should be given to pip
• Do not require wheel and numpy for building
• Add deploy_check workflow which uploads PSYDAC to TestPyPI from a pull request into the main branch
• Add deploy workflow which uploads PSYDAC to PyPI after a merge into the main branch

I can't say much about the workflow files, but it looks good to me.

Btw, what is the reason for the folder structure? Having .github/actions with subfolders and .github/workflows?

Thanks for the review!

The folder structure is the one required by GitHub Actions, I cannot say why they designed it that way 🤷‍♂️
