fix(biome_graphql_parser): allow keyword to be used as identifier

[vohoanglong0107]

Summary

It's hard to believe, but GraphQL allows using keyword as identifier. This means that the parser must be able to handle a GraphQL query like this:

query enum($true: false) {
  null
  mutation
  enum Direction @deprecated {
    NORTH
    WEST
  }
}

This means many assumptions made when handling parsing errors are no longer applicable. In the above example, suppose the query misses the closing brace:

query enum($true: false) {
  null
  mutation
  enum Direction @deprecated {
    NORTH
    WEST
  }

This could either mean the entire expression is a giant query, or there is a query and an enum definition, depending on where the users want to put the closing braces.

This PR adds support for using keywords as identifier, and removes several assumptions made when handling errors.

Test Plan

All tests should pass.
