rename MANUAL_DIV_CEIL MSRV alias and add missing conf info for manual_div_ceil (#14263)

- The name of an MSRV alias should describe its functionality, and it is
not appropriate for it to be the same as the name of the lint that uses
it.
- Additionally, while `manual_div_ceil` allows setting MSRV, this is not
correctly reflected in the configuration information.
