Fixes: #61904
This updates ESM data URL MIME extraction regexes to remove overlapping quantifiers that allow super-linear backtracking.
(?:[^,]*?)(;base64)?,with(?:;[^,]*)?,in:lib/internal/modules/esm/get_format.jslib/internal/modules/esm/load.jsBehavior is preserved for existing valid/invalid
data:URL shapes while avoiding pathological backtracking on crafted inputs.
