bracket quote will be mapped to "DEFAULT"

> Issue Type: Bug
> Components: core
> Affects Versions: 1.17.0, 1.18.0
> Reporter: Nan Deng
> Priority: Major
>
> From CALCITE-1217 I found this statement:
> {code:java}
> (Calcite) Its default identifier quoting character is double-quote.
> {code}
> this is not consistent with what's been said in
> [Parser.jj|https://github.com/apache/calcite/blob/50012d221d6e9a5e42a957ab0723e0f706b25be3/core/src/main/codegen/templates/Parser.jj#L6976]
> which defines bracket as the default identifier delimiter:
>
> It should be one or another.
