misleading QueryError on misspelled labels or kinds

[OmarTawfik]

Query::parse(
        "[FunctionDefinition
            ...
            @name Name: [_]
            ...
        ]",
    )
    .unwrap()

Error:

QueryError {
    message: "Parse error:\nexpected ']' at: @name Name: [_]\n            ...\n        ]\nAlt at: [FunctionDefinition\n            ...\n            @name Name: [_]\n            ...\n        ]\nAlt at: [FunctionDefinition\n            ...\n            @name Name: [_]\n            ...\n        ]\n",
    row: 0,
    column: 0
}

• Query is fixed by replacing Name: with name:.
• Same error message happens when misspelling kinds.
• Instead of rejecting the whole identifier as an invalid nom alternative, maybe we can parse the identifier, and produce an error (at the identifier location) explaining why it is not a valid TerminalKind, NonterminalKind, or NodeLabel?
