Treat imported header same as table.header

[Andrew15-5]

If I import table: * and use header in table(), then it will group the cells incorrectly, by counting the header as the first cell. With table.header the grouping works as expected. Same goes for grid.

We may simply expand our recognition list by treating header the same as table.header 🤔

At present, semantic information has not been utilized to recognize table-related functions.
If we have knowledge of functions marked table-like, cell-like, and header-like, we can handle the table structure more precisely.
It could introduce many false positives if we only recognize them by name.

The identifier resolution is actually solved by tinymist-query. The only question here is that whether it is fast enough to be used for formatting API. I guess it is not to expensive, as we have already used them in semantic highlighting (semantic tokens).

We can limit it's usage for table formatting only for now. I think it would worth it
