fix(treesitter): highlight group for EditQuery captures #36265

fix(treesitter): more distinctive highlight for EditQuery captures

Problem: EditQuery shows captures in the source buffer using the Title
highlight group, which could be too similar to Normal.

Solution: Use a virtual text diagnostic highlight group: they are
displayed in a similar manner to the query captures so we can assume
that the color scheme should have appropriate styling applied to make
them visible.
