Update sql dll to support RETURNING

[enaaab460]

Description

I spent many hours trying an sqlite command (db_connector/sqlite) using RETURNING keyword and failing, even though it worked using sqlite directly.
Then I discovered that the sql dll in nim/bin is 3.31 which does not support RETURNING.
So add the latest sql please

Nim Version

2.2.0

Current Output

Error dbError near RETURNING
(paraphrased)

Expected Output

No response

Known Workarounds

Manually updating it to the latests 3.48 fixed it

Additional Information

I could not find sql dll in any of your repos, so not sure where to put this bug report
