yamllint: cover all changed files ending in yaml, yml or fmf

[vojtapolasek]

Description:

• update the ci-lint workflow to utilize .yamllint config file present in the root of the project
• update the .yamllint config file to implement some of project's style requirements
• apply yamllint to all files which are being changed by a PR, let yamllint ignore files which are not matching yml, yaml or fmf extensions

Rationale:

• The previous grep "controls/" pattern matched any file path containing controls/, which could include non-YAML files that yamllint cannot process. Restricting to controls/.*\.yml ensures only relevant YAML files are linted, avoiding spurious CI failures.

Review Hints:

• Single-commit, single-line change in .github/workflows/ci_lint.yml (line 52).
• No product builds are affected — this is a CI infrastructure change only.

There is a similar regex on line 32. Should that regex be changed as well?

Are you sure you don't want to configure yamllint properly instead, as I suggested in #14529 (comment) ?

@vojtapolasek Do I understand it well that now the .profile files won't be checked?
