Bumps sqlparse from 0.4.3 to 0.4.4.

Changelog

Sourced from sqlparse's changelog.

Release 0.4.4 (Apr 18, 2023)

Notable Changes

• IMPORTANT: This release fixes a security vulnerability in the parser where a regular expression vulnerable to ReDOS (Regular Expression Denial of Service) was used. See the security advisory for details: https://github.com/andialbrecht/sqlparse/security/advisories/GHSA-rrm6-wvj7-cwh2 The vulnerability was discovered by @​erik-krogh from GitHub Security Lab (GHSL). Thanks for reporting!

Bug Fixes

• Revert a change from 0.4.0 that changed IN to be a comparison (issue694). The primary expectation is that IN is treated as a keyword and not as a comparison operator. That also follows the definition of reserved keywords for the major SQL syntax definitions.
• Fix regular expressions for string parsing.

Other

• sqlparse now uses pyproject.toml instead of setup.cfg (issue685).

Looks like sqlparse is up-to-date now, so this is no longer needed.
