Add support for nested tags

[huy-vuong]

Context

Other note-taking setups like with Bear and Notable have the ability to nest tags such as #ideas/foam to indicate "ideas specifically for Foam".

The nesting is denoted by the / character, like a directory, so this should be able to work in either #hashtag form or in the YAML frontmatter.

This way, it'd be easier to group similar ideas together and instead of just searching for "ideas", you could search for "ideas specifically for Foam" for instance.

The Tag Explorer might look something like this:

• #️⃣ ideas
  • #️⃣ foam
    • 📝 Add support for nested tags

Current Behaviour

• In the Tag Explorer:
  • #ideas/foam gets treated as just having the tag #ideas.
  • Adding the tag ideas/foam to the frontmatter gets treated as just having the tag #ideas.

Desired Behaviour

• In the Tag Explorer:
  • #ideas/foam gets treated as having the tag #ideas.
  • #ideas/foam also gets treated as having the tag #ideas/foam, which is nested inside #ideas.
  • Adding the tag ideas/foam to the frontmatter gets treated as just having the tag #ideas.
  • Adding the tag ideas/foam to the frontmatter also gets treated as just having the tag #ideas/foam, which is nested inside #ideas.
