Steps to reproduce

1. Goto into the Indexer Menu in the Admin Interface
2. Observe that customer_grid mode is by default "Update on Schedule"
3. Observe when set to "Update on Schedule" marked green.
4. Change Indexer Mode for customer_grid to "Update on Save"
5. Observe that the indexer mode is now red coloured

Expected result

The customer_grid index is set to "Update on Save" by default and also the mode entry is marked red when set to "Update on Schedule" and marked green when set to the correct mode "Update on Save"

Actual result

With the upgrade to 2.4.8-p1 the customer_grid index is set to "Update by Schedule" by default. Also the entry is marked green.

Update on Schedule does not work for customer_grid index

This has changed in Magento 2.4.8, see the release notes:

Customer Grid indexer does not work properly in Update by Schedule mode
Earlier Customer grid was updated instantly but after the fix Customer grid is updated after cron run but not reflect instantly.
AC-13810 - GitHub code contribution

So it makes sense that the default is now Update By Schedule and that it's in green, no?

What does need to happen, is that the documentation should be updated to mention "Before Magento 2.4.8, the customer grid indexer ..."
