chore(package.xml): bump version to 0.38.0

[youtalk]

Description

This PR is based on https://github.com/orgs/autowarefoundation/discussions/5292 and aims to manage the versioning of autowarefoundation/autoware.universe using ROS package release tools.
All package versions have been unified to 0.38.0 following https://github.com/tier4/autoware.universe/tree/v0.38.0.

Note that this PR is a merge request not for the main branch, but for the newly created humble branch. Once this PR is merged, I plan to tag 0.38.0 on the humble branch and create a PR to merge the differences into the main branch as well.

Currently, I was manually running the ROS package release tools to create PR, but in the future, we would like to modify https://github.com/tier4/autoware-release-scripts to automate this process.

@mitsudome-r @xmfcx A branch protection rule is needed for the humble branch. Please set it up with conditions similar to those of the main branch, but it should allow merge commits rather than squash merges.

@youtalk -san, I can add the branch protection rules.

but it should allow merge commits rather than squash merges.

Why? We could have the releases and version control without needing merge commits.

I've checked the practices utilized by many official ROS 2 packages and none of them allowed merge commits.
They were versioning and backporting by keeping a linear history just fine.

I'd much prefer not to complicate the commit history by allowing merge commits. And keep a linear history for main and ros-distro branches.

By the way, I've added the same rulesets as main for humble.

@xmfcx If we merge all patch PRs that exist only in the humble branch into the main branch with individual PRs, squash merging will still be fine going forward.
Please review this! cc @mitsudome-r

I have confirmed that the changes are only made to package.xml and CHANGELOG.rst.

For the package.xml, the PR is only updating version to 0.38.

I haven't looked into all the details of each CHANGELOG.rst, but I don't think there is a necessity to review them in details since they are generated automatically. We can always update them if we notice a package with wrong changelogs.

OK for my pkgs
