feat(universal-addon): add helm lint and README generation

[atyu1]

Description

Add support for:

• Helm charts linting
• Helm Readme generation

Helm chart linting is universal and automatically checks all directories inside, if presents in repo which are called: charts
Helm Readme generate README

Both does not fail, if repo does not have custom chart.

New tools added to .tools-version to support it

Type of change

• A bug fix (PR prefix fix)
• A new feature (PR prefix feat)
• A code change that neither fixes a bug nor adds a feature (PR prefix refactor)
• Adding missing tests or correcting existing tests (PR prefix test)
• Changes that do not affect the meaning of the code like white-spaces, formatting, missing semi-colons, etc. (PR prefix style)
• Changes to our CI configuration files and scripts (PR prefix ci)
• Documentation only changes (PR prefix docs)

How Has This Been Tested?

• pre-commit tested in repo where we have custom chart and it lints and failes if linting is not passing, also README generated automatically
• pre-commit tested in repo, if does not have helm chart, all passing, for example for external-secrets:

~/code/github.com/lablabs/modules/new/terraform-aws-eks-external-secrets
