# What ❔

Replaces outdated ::set-output.
Removes unneeded secret.
Marks ssh public key as sensitive.
Fixes comments.
Uses ubuntu-22.04-github-hosted-16core runner for slow workflows.
<!-- What are the changes this PR brings about? -->
<!-- Example: This PR adds a PR template to the repo. -->
<!-- (For bigger PRs adding more context is appreciated) -->

## Why ❔

To correspond public repo standards.
<!-- Why are these changes done? What goal do they contribute to? What
