feat: all --octoherd-* flags are now optional (#3)

BREAKING CHANGE: Repositories can no longer be passed as positional argument, use the \`--octoherd-repos\` (or \`-R\`) CLI flag instead.

Before:

```
npx @octoherd/script-add-octoherd-cli-to-script "@octokit/*"
```

After

```
npx @octoherd/script-add-octoherd-cli-to-script --octoherd-repos "@octokit/*"
```

Or do not set `--octoherd-repos` at all, in which case the user will be prompted.
