Incorrect usage examples for --download-source

[nsamarin]

Minor issue, but your documentation states that you should do, e.g.:

apkeep -a org.mozilla.fennec_fdroid -d f-droid .

which does not work:

error: 'f-droid' isn't a valid value for '--download-source <download_source>'

because the actual names of accepted download-sources are defined as:

pub enum DownloadSource {
    APKPure,
    GooglePlay,
    FDroid,
}

so the example should be:
apkeep -a org.mozilla.fennec_fdroid -d FDroid .

@nsamarin thanks - the documentation is aligned with the latest commit in the repository, but not the latest release. As of the next release, this will be resolved.

By "resolved" I mean the usage will change to invoke the download source with f-droid

That's great, thank you for the prompt response as well!
