Setup dependabot for github-actions and codespell (#9857)

This sets up  dependabot to check weekly updates for pip and github-actions dependencies.
If it finds an update it will create a PR to update the dependency. More information can be found here

It includes the update of:

* vmactions/freebsd-vm from 0.1.4 to 0.1.5
* codespell from 2.0.0 to 2.1.0

Also includes spelling fixes found by the latest version of codespell.
Includes a dedicated .codespell folder so dependabot can read a requirements.txt file and every files dedicated to codespell can be grouped in the same place
