DB2 provider throws exception over _query method incompatibility

[lkrms]

Description

This issue was introduced by ADOdb 5.22.6 and appears as soon as a connection to DB2 is attempted. Hopefully self-explanatory:

Declaration of ADODB_db2::_query(&$sql, $inputarr = false) must be compatible with ADOConnection::_query($sql, $inputarr = false)

Environment

• ADOdb version: v5.22.6 (via Composer)
• Driver or Module: DB2
• Database type and version: n/a
• PHP version: 8.2.6
• Platform: macOS/Linux

• I have tested that the problem is reproducible in the latest release

Regression introduced by #966 - looks like I forgot to update function declaration for the db2 driver, sorry about that.

As a quick workaround for now, just remove the offending &, it's not needed.
