Fix parsing ALTER TABLE ... ADD COLUMNS (...) (#2087)

njaremko · web-flow · commit 229099c74b92 · 2024-10-24T08:11:46.000+07:00
The current behaviour fails when it encounters `ADD COLUMNS` and merges
everything in the `()` into one string with no whitespace.

So `ALTER TABLE catalog.table.name ADD COLUMNS (apples int)` becomes
`ALTER TABLE catalog.table.name ADD COLUMNS (applesint)`.

This commit adds an understanding of how `ADD COLUMNS` to the grammar.
