Add in-repo rollback functionality

[melody-universe]

User executes a workflow called "Commit Rollback"

• Provides a single solution name
• Commit hash OR
• Version Number

[melody-universe]

Generate a README.md in each solution folder to browse the commit history for that solution and (if possible) provide a link to run a rollback commit for each version

Example:

Version	Date	SHA	Browse	Rollback
1.0.0.0	Thu Feb 3 11:31:39 2022 -0800	a6adc52a044887c6e2fafdeda2cd5e2f5eff50e2	browse	rollback
1.0.0.1	Thu Feb 3 11:31:39 2022 -0800	a6adc52a044887c6e2fafdeda2cd5e2f5eff50e2	browse	rollback
1.0.0.0	Thu Feb 3 11:31:39 2022 -0800	a6adc52a044887c6e2fafdeda2cd5e2f5eff50e2	browse	rollback

This is nice, but for now just implement the workflow.
