Problem in new rights rext

[dbeyer]

One of the new pieces of rights texts has the following: All others Request permissions from owner/author(s).

https://github.com/borisveytsman/acmart/blob/v2.00/acmart.dtx#L5959

To me this looks like a copy-paste mistake.

From the context, it seems that All others was meant to be overwritten and it should read only: Request permissions from owner/author(s).
