fix: Selecting around " while cursor is on " will no longer error

[nik-rev]

Previously, if you had a file like this:

"ui.text" "example"

Having cursor on the 2nd " will give an error: Cursor on ambiguous pair

With this PR, it won't error anymore and it will highlight the entire "ui.text" correctly. This fall-back works for files with tree-sitter support. For files without, it will just have the old behaviour

Closes #12478

[robinmoussu]

It fixes #12478 but not #12454. If your cursor is on the right quote (either simple or double), mim/mam will still select inner/outer block one level above.

Thanks, I'll remove that mention now!
