* Update ubuntu-latest tag to ubuntu-22.04
Everytime a CI service such a GitHub actions update the images
corresponding to their 'latest' tags, pipelines tend to have some
hipcups due to changes in the distribution default packages.
By fixing the images to a specific one, we should be more resilient to
changes in the Github actions environment.
* Use same build directory used in CMake presets
* Create codeql-analysis.yml
* Add main branch.
* Update to latest boilerplate.
* Replace schedule with workflow_dispatch, so that it can be triggered manually.
