axe-core does not recognize scope="rowgroup" and scope="colgroup" as row and column headers

### Product

axe-core

### Product Version

4.6.3

### Latest Version

- [X] I have tested the issue with the latest version of the product

### Issue Description

#### Expectation

I expect axe-core to treat `th[scope="rowgroup"]` as a row header and `th[scope="colgroup"]` has a column header. A couple of ways this manifests itself is when using the `axe.commons.table.getScope()`, `axe.commons.table.isRowHeader()` and `axe.commons.table.isColumnHeader()` methods.

#### Actual

It treats the scope of these headers as "auto".

#### How to Reproduce

1. Go to the "Table with Two Tier Headers" example at https://www.w3.org/WAI/tutorials/tables/irregular/
2. Inject axe-core into the page
3. In the inspector, select the "Mars" header
4. Run `axe.commons.table.getScope($0)`
- Output is "auto"
5. Run `axe.commons.table.isRowHeader($0)`
- Output is `true`

#### Additional context

I believe this can be resolved by including `rowgroup` and `colgroup` as appropriate in the following places
