* linode: Allow templating token for dynamic inventory

Template the value for the access_token if it's a Jinja template.

Allows for looking up tokens from files or pulling from secrets stores like Vault.

* add Linode changelog fragment

* Fix lookup example for newer versions of Ansible

Co-authored-by: Felix Fontein <felix@fontein.de>

* Rename test case for clarity
