❇️ Add Julia support

### Language Name

Julia

### Tree-Sitter Grammar

https://github.com/tree-sitter/tree-sitter-julia

### I will work on this

No

### Additional Info (optional)

I would be lovely to have Julia support! It is the only crucial thing that is missing from CodeEdit to have me switch to it. I am afraid that I couldn't help as I do not know Swift at all and currently doesn't have time to invest into it.
