Start ESM Conversion

[NullVoxPopuli]

Resolves: https://github.com/josemarluedke/remark-hbs/issues/27

This is a breaking change.

• ESM only

• Drop node < 14

  This will also begin the ability to support hljs v11 and hifi glimmer highlighting in Docfy. (hbs highlighting is terrible)

Currently, all tests failing, potentially due to AST changes
