v0.2.2 Run in Temporary Directory

Fixed

• Name clashes during migration for checkouts when a file or directory has the
  same name as the branch being checked out

Changed

• The action now operates in a temporary directory that is a copy of the
  directory the action was called on. Using a temporary directory ensures that
  any operations of the action, such as git operations, do not change the state
  of the files and directories any following steps receive.
