Automate the go version update

[v1v]

What does this PR do?

Delegate the update for the go-version to be done automatically.
I used #26186 as a reference for the implementation

You can use this script locally:

.ci/bump-go-release-version.sh <new-go-version>

NOTE: it will add and commit the changes in the existing branch. The push and PR creation is not done within this script.

Why is it important?

No more manual actions.

Further details

This automation will not merge the PR automatically, neither it will create any backports nor changelog entries
We do want the teams to do so:

• Review the changes and validate the CI status
• Add entry in the CHANGELOG-developer.next.asciidoc
• Create the relevant backports either with mergify or manually with some other tooling.

This particular automation will run on weekly basis. The pipeline is bump-go-release-version-pipeline

Nice, that will be helpful.

About auto-updating:
For patch releases the release notes should still be inspected. Fixed bugs that do affect Beats might be added to our changelog. Security fixes need some special attention.
Minor releases are not frictionless. We sometimes need to add workarounds for breaking changes or run into other issues with go modules. This is unfortunately a very manual process.
