Use single quotes in sql string literal (#13968)...

Use single quotes in sql string literal (#13968) the SQL spec requires that string literals use single quotes and column references (or other identifiers) use double quotes. sqlite permits the use of double quotes for string literals in "unambiguous cases". For some reason, its understanding of what constitutes unambiguous has changed recently - I'm on FreeBSD 14.0-CURRENT with sqlite 3.41.0 - and attempting to do anything with ipython throws a very strange sqlite operation error: ``` [+] ~% ipython --version (test) audrey@daisy [12:18:02 AM] 8.11.0 [+] ~% ipython (test) audrey@daisy [12:18:04 AM] [TerminalIPythonApp] ERROR | Failed to create history session in /usr/home/audrey/.ipython/profile_default/history.sqlite. History will not be saved.

Type '?' for help. ``` This patch fixes it. idk if this constitutes a bug in sqlite3, but this is, I guess, more correct.
