fix(ci) fix php8.5 Warning: unexpected NAN value was coerced to string

When binding a NAN value to a prepared statement parameter, PHP 8.5 emits a warning: "unexpected NAN value was coerced to string". This warning is not present in PHP 8.4, where the value was silently converted to the string "NAN" and handled correctly by PostgreSQL.
