Make JSON validation schema a standalone JSON file inside the repository.

[ssbarnea]

In order to allow other tools, libraries or catalogs to use and refresh the JSON validation schema for build, the file should be hosted inside the project source tree and not embedded in a python file like

ansible-builder/src/ansible_builder/ee_schema.py

Line 197 in 5a748e0

schema_v3 = {

Including the JSON in the package and reading it is very easy.

Please note that this blocks ansible/ansible-lint#3421 which should happen before next AAP release if possible.

If your schedule is tight, I can probably persuade someone from devtools team to make a PR that does this for the builder.
