feat: add pijul_channel module (#4765)

* feat: Pijul VCS support

* Extra bits needed for new module.

* Format Markdown table.

* Fix lint.

* Don't test Pijul module so thoroughly.

Installing from source is too expensive, and compiled binaries are only
available for Windows (and unofficially as well). Perhaps once Pijul
1.0.0 comes out of beta there will be more binaries available in package
  repos.

* Format!

* Bad rebase, remove Pijul install from workflow.

* Mock Pijul commands for code coverage.

* Make fake .pijul directory in fixture.

* Truly mock `pijul` command.

* Rename module from `pijul` to `pijul_channel`.

* Format!

* Fix config-schema.json.

* Missed changing module name in docs/ folder.
