Set up tab completion for Redocly CLI

Give your redocly command superpowers by adding tab completion to your terminal. Run the command to generate the completions, then add the output to your .bashrc or equivalent file.

Generation the completion script:

redocly completion

The command output contains installation instructions. For example, to install the completion script in bash, use:

redocly completion >> ~/.bashrc

The approach is similar for other shells. After the installation, restart your terminal for the changes to take effect.
