insert_link yields incorrrect results (missing $/) for relative file paths

[ziontee113]

Hi @max397574 , thank you for creating this awesome plugin.

The issue: let's say we have this folder structure, and I'm in the 2022 Jul 25 file:

If I run Telescope neorg insert_link, and pick one of the headers in rust.norg in the examples folder, the result will be:

{:examples/rust:* Programming in Rust}[Programming in Rust]

Which won't work.
The correct result should be:

{:$/examples/rust:* Programming in Rust}[Programming in Rust]

It's odd that Telescope neorg insert_file_link handles this well. This must be a bug fore insert_link.
