Enhancement: add parent directory to recently modified files list

[grahampcharles]

In hugo (and maybe other SSGs?), content is kept in an index.md file within a titled bundle directory. Therefore, the "Recently Modified" list on the FM toolbar generally lists only multiple instances of index.md. Adding the immediate parent directory would give more context.

Makes sense! Thanks for proposing the enhancement.

When using index.md files, the parent folder will now be shown.
