Fixes the issue of [br] bbcode's weren't rendering new lines.

Can you share some examples of where that happens so I can validate the behavior + the fix?

Of course.

This happened every time I added "##" documentations to functions and hovered over them. [br] tags rendered like they were inside a [code] tag.

For example:

## A test function. [br]
## Testing.
func test():
    return true

Rendered hover documentation like:
"A test function. br Testing."

While the expected behaviour is:
"""
A test function.
Testing.
"""

Oh, I get it. I didn't notice at first that you were adding the [br] tag, I was trying to think of why the language server would send bbcode line breaks and I was very confused.

Are you doing that to work around the fact that Godot 4 seems to not separate multiple lines of doc comments?

@Calinou @ryanabx Is this a bug in the G4 language server? G3 returns doc comments without concatenating them:

Yep, that's what I meant to fix somehow.
