fix: improve detection of regexp vs division

[DylanPiercey]

Description

Improves the detection of division vs regexp expressions to assume division when the preceding character is a quote. This improves parsing of css grid properties in particular.

Note in the future this could probably be improved to remove the regexp state altogether for non script sections, but that would require a larger refactor.
