Describe the bug

When you try to change the Checkout endpoint to "check" it appends "-2" automatically

To reproduce

Steps to reproduce the behavior:

1. Newly install WP installation and set up Woo
2. Try changing the endpoint for checkout to "check" (WooCommerce > Settings > Advanced > Page Setup > Checkout > Try changing the endpoint from "checkout" to "check")
3. This would append "-1" automatically, so it looks like "check-2"

I'm unable to reproduce this locally.

WordPress would append -2 if an existing page with that slug already exists, so check for that?

Thanks for the report @namiokuzono. I've just seen this issue and can confirm it was noticed and fixed in #10640, so the latest release of blocks should have cleared this up.

Thank you
