Improve SQL parser on dolthub

We rely on [`node-sql-parser`](https://github.com/taozhi8833998/node-sql-parser) heavily on dolthub to parse queries on dolthub, mostly for generating queries for the cell buttons and determining whether a query should create a workspace. `node-sql-parser` has a lot of bugs and has led to a bunch of errors on dolthub (specifically in parsing a query to determine if a workspace should be created for mutation queries).

It would be a lot of work to replace `node-sql-parser` and there's a ton of code written around it, but we need to improve. Some options:
1. Fork `node-sql-parser`, find a bunch of mysql queries we can test against, fix it ourselves
2. Find another sql parser and replace the existing dolthub code

It's not really urgent, but we need a better long term option
