HeaderContext and CellContext types should use ReactTable

[kevinpastor]

TanStack Table version

9.0.0-alpha.32

Framework/Library version

react@19.1.0

Describe the bug and the steps to reproduce it

When defining cell or header in the column definitions, the type of the props provided, CellContext and HeaderContext respectively, is inaccurate. The type of the table prop should be ReactTable instead of Table. Without, a cell cannot use table.Subscribe that became available in the alpha 9.

In the example, you can see in the logs that the table provided as prop does actually have the properties.
