fix(cost-management): use dots instead of slashes in menuItems keys (#3022)

* fix(cost-management): use dots instead of slashes in menuItems keys

RHDH expects dots as path separators in menuItems keys (e.g.,
`cost-management.optimizations`), not slashes. Using slashes causes the
menu items to appear as flat top-level entries instead of being nested
under the "Cost management" parent menu.

+Fix `menuItems` keys in `app-config.dynamic.yaml` to use dots instead of slashes as path separators, so that "Optimizations" and "OpenShift" are properly nested under the "Cost management" parent menu in the RHDH sidebar.
