fix: Allow column names that have to be quoted

[czindel-sap]

Following statement should be possible with the proposed change

await INSERT.into ("ENTITY_COL_BEGIN_WITH_NUMBER") .entries ({
  ID: 100,
  "1VALUE": 1,
});

currently this ends up with this error

Error inserting into ENTITY_COL_BEGIN_WITH_NUMBER Error: argument type mismatch: not supported path expression: Support only * or <KEY NAME>
-> $.1VALUE
->   ^

@johannes-vogel It looks like the tests are not executed or stuck, is there something that I need to do?
