Simplify release workflow

[jprendes]

This PR attempts to simplify the release CI workflow.
The main changes are:

• The release tar files are generated during the Build step, removing the need to manipulate the mode of the executable files
• The Create Draft Release step uploads all the tar files generated during the Build, making it easier to scale to more variants (e.g., x86_64, aarch64, glibc, musl)
• Modev the content of the tar file to the rood, i.e., inside the tar moved from /youki_0_4_0_linux/youki-0.3.0/youki to /youki
• The release tar files are renamed from youki_0_4_0_linux-x86_64.tar.gz to youki-0.4.0-x86_64.tar.gz
• Use the gh CLI command provided by GitHub to create the release instead of the third party softprops/action-gh-release

As an example of the release generated by this PR see https://github.com/jprendes/youki/releases/tag/v0.4.0

It seems that the structure of the uploaded tar has been changed, which may affect #2510. Should I keep the previous structure first and then make corrections in the next PR? @jprendes

Sorry, but could you fix the conflict with #2510?

Rebased!
Sorry it took so long, I've been really busy.

[jprendes]

Oh, sorry, I just noticed that this also affects basic_setup.md and release_tag.sh.

Will fix that now

Edit: basic_setup.md should not be updated until we do a new release.

@utam0k @cuisongliu PTAL :-)
