Correctly parsing non Leaf `#` tag.

[Hailong]

Leaf templates containing # characters that don't match a tag will be rendered. This allows for things like anchor and colours to work correctly.

Also adds a new #comment tag

Resolves #89

@Hailong thanks for this, honestly not sure how it was such a simple fix 😅

Could you change https://github.com/vapor/leaf-kit/blob/main/.github/workflows/test.yml#L24 to point to main instead of master - that should get CI working

Original comment:

It includes the following changes:

• Literally output the non Leaf # tags.
• Add the explicit support for #comment tag.
• Enable the corresponding unit test.
