fix: render rulers before the cursor

Render rulers before the cursor to ensure that the cursor, when over
a ruler, is not hidden from view. Without this, you typically end up
with 1) foreground text that is the same as the background if the
ruler doesn't already have a foreground and 2) no visible cursor,
because the ruler's background color took precedence. By moving the
rulers before the cursor, this ensures that the theme is still rendered
more or less the way one would visually expect things to turn out.

Related to helix-editor#7371. Not submitting this as a patch
because it doesn't seem like this is the desired solution, but it
thankfully works perfectly for me.
