Update application backup settings

[enggnr]

• What kind of change does this PR introduce? (Bug fix, feature, docs update, ...) Adds folder locations to back up apps using Mackup for the different plaforms

• What is the current behavior? (You can also link to an open issue here) This is done differently but it is not sufficient to address the various locations that can be used to store app settings (which depends on the installation method)

• Other information: Fixes #129

NOTE

• Logitech Options+ does not install when using Chocolatey. This needs to be revisited once that is working to add the correct path
• Tor-browser does not install when using Chocolatey. Tested this by creating a local package, may need to revisit once it is working without having to do the manual fix

@ProfessorManhattan, this is complete.

Hey @enggnr -- sorry about this but can you reformat the commit to use the new _env: parameter that you can search for on other entries? Please commit the updates right to master because merging software.yml is tricky since I keep updating it. Also, please add the variables into home/dot_config/shell/apps.sh.tmpl as well as home/dot_config/autorestic. You can open a seperate PR or just merge it all to master directly since it is all pretty straight forward.

@ProfessorManhattan, added missing values in home/dot_config/shell/apps.sh.tmpl in the commit https://github.com/megabyte-labs/install.doctor/commit/1bb6448302534f41cf5cc2e6a5d4fed189a494d5.

Do we want the _link fields that were added as part of this PR in the master branch? These were created following this README. If they are needed, I'll add them and the values of _env fields where missing.
