Add commit message extraction and cleaning to commit symbol replacement

- should include commit message below the heading "# Commit [hash]". When encountered ascii tree in the commit message, remove it
- place remove_ascii_tree in `apps/editor/src/utils/ascii-tree/ascii-tree.ts`
- rename remove_ascii_tree to 'strip from text'
