fix(sqlite): support all sqlite pragma statement

[vbehar]

What was changed

• I removed the extra underscore in the key
• I removed the pragma key check

Why?

• the extra underscore was breaking the pragma support, because sqlite couldn't recognise the pragma key
• the pragma key check was too restricting, users should be able to configure any pragma statement from https://www.sqlite.org/pragma.html - removing the check all to use any pragma, without adding more work to maintain an hardcoded list

Checklist

1. Closes [Bug] Sqlite pragmas are not applied correctly #681

2. How was this tested:

manually:

• by running ./temporal server start-dev --db-filename temporal.sqlite --sqlite-pragma journal_mode=WAL --sqlite-pragma synchronous=NORMAL --sqlite-pragma busy_timeout=5000
• and ensuring that 3 files have been created: temporal.sqlite, temporal.sqlite-shm and temporal.sqlite-wal

3. Any docs updates needed?

no, because it's just a bug fix. the docs are already there.

Thanks! Will confer with team just to make sure there wasn't a reason we were limiting the pragmas. I don't see anything obvious at temporalio/temporalite-archived#30 at first glance.

Interesting, I suspect we just didn't have test cases. Would you be willing to add a test (or adjust an existing one) that just adds any innocuous pragma just to ensure it works?

[vbehar]

Sure, I'll add one
