[docs] : Broken links in COMPONENT-OWNERS.md for cloudnative-pg project

[Akash3121]

Multiple links in the cloudnative-pg section of the COMPONENT-OWNERS.md file are currently broken (404). They appear to have been incorrectly prefixed with the charts repository path.

Repro:

Go to documentation section in component owners

Click on the links for cloudnative-pg/docs -> give 404 error.

Broken link found:

• Documentation points to https://github.com/cloudnative-pg/charts/tree/main/cloudnative-pg/cloudnative-pg/docs
• OLM points to http://github.com/cloudnative-pg/charts/tree/main/cloudnative-pg/cloudnative-pg/config/
• Testing points to https://github.com/cloudnative-pg/charts/tree/main/cloudnative-pg/cloudnative-pg/.github, https://github.com/cloudnative-pg/charts/tree/main/cloudnative-pg/cloudnative-pg/hack, https://github.com/cloudnative-pg/charts/tree/main/cloudnative-pg/cloudnative-pg/tests for github, hack, tests respectively

Expected fix:

• Documentation link should point to https://github.com/cloudnative-pg/cloudnative-pg/tree/main/docs
• OLM link should point to https://github.com/cloudnative-pg/cloudnative-pg/tree/main/config
• Testing
  • .github link should point to https://github.com/cloudnative-pg/cloudnative-pg/tree/main/.github
  • hack link should point to https://github.com/cloudnative-pg/cloudnative-pg/tree/main/hack
  • tests link should point to https://github.com/cloudnative-pg/cloudnative-pg/tree/main/tests

Happy to create a PR for this fix!
