gcli command auto completion and arm64 build

- Added detailed instructions for generating the completion script and registering it for your shell when calling `gcli completion --help`
- Added that information in the CHANGELOG.md
- Moved `indoc` crate dependency in Cargo.toml to make it explicit it's now also used outside of tests.

 ### Added / Changed
 - Extra command `completion` added which takes a `--shell` argument to generate a completions script for a specified shell.
+  - Calling this command with `gcli completion --help` will provide detailed instructions to generate the completion script and register it for your shell (not necessary when using the `.deb` package that include and registers the completion scripts for `bash`, `zsh` and `fish`)
 
 ### CI/CD

+		The base completion scripts for `bash`, `zsh` or `fish` are already registered when installing the `.deb` package.

+		  mkdir -p ~/.local/share/gcli
+		  gcli completion --shell bash > ~/.local/share/gcli/completion.bash
+		  # Direct test - gcli should have the completion after the source command
