runtime(sh): fix spurious nextgroup=shComment on shEscape
Remove `nextgroup=shComment` from the `shEscape` syntax pattern.
This was causing `#` characters after escape sequences inside
double-quoted strings to be misinterpreted as comments, breaking
highlighting for the rest of the file.
Add a test case for escaped characters followed by # in double quotes.
fixes: #19053
closes: #19414
