Rollup merge of #48857 - Songbird0:improve_column_macro_documentation, r=joshtriplett

Browse Source 
Modify part of `column!` documentation.

Just like `line!` documentation, I've replaced:

> The returned column is not the invocation of the `column!` macro itself

By

> The returned column is *not necessarily* the line of the `column!` invocation itself

See #46997.
