Set noble as default ubuntu distribution.

Adding noble as default ubuntu distribution.

This shouldn't affect iron or humble as they seem to override this value:

ci/create_jenkins_job.py

Lines 462 to 463 in 272db18

	'ros_distro': 'humble',
	'ubuntu_distro': 'jammy',

ci/create_jenkins_job.py

Lines 476 to 477 in 272db18

	'ros_distro': 'iron',
	'ubuntu_distro': 'jammy',

As it stands, the one reason we can't do this is because python3-flake8 is still broken in Noble. @j-rivero is working on getting that solved in Noble proper, and @claraberendsen may be working on a workaround (by pulling the package from noble-proposed) for the short-term.

[claraberendsen]

@clalancette @marcoag This is the branch to run ci with flake8 from noble-proposed instead of noble. However there seems to be a new error there related to python.

Before we can merge this one in, we need #766 and some of the fixes from #761 as well.

[wjwwood]

lgtm pending #761

[clalancette]

All right, I believe that we have everything we need now. Here is CI on Noble with the current state of the repository:

• Linux
• Linux-aarch64
• Clang

[clalancette]

Bah, we still need another PR. See #769

[clalancette]

All right, all CI for this was done in #769 . I'm going to approve, merge, and then deploy this change so we start using Noble as the default for CI.

[clalancette]

And this has now been deployed.
