Describe the bug

gh repo create provides --enable-issues and --enable-wiki long options, but the usage text notes these options are (default true). There's no apparent way to invert these options

$ gh --version
gh version 1.5.0 (2021-01-21)
https://github.com/cli/cli/releases/tag/v1.5.0

Steps to reproduce the behavior

$ gh repo create --no-enable-issues test
$ gh repo create --disable-issues test
$ gh repo create --enable-issues false test

Expected vs actual behavior

I'd expect a documented way to actually create a repo issues or wiki disabled. All three imaginary inverted versions of --enable-issues and --enable-wiki produce an error.
