Setting `README.md` in CLI

I cannot seem to set the location of `README.md` with the CLI. When I go to my repo root, and run the command:

```
yarn all-contributors generate --config /Users/mcranmer/Documents/PySR/.all-contributorsrc
```

I get the error:

```
warning package.json: No license field
$ /Users/mcranmer/node_modules/.bin/all-contributors generate --config /Users/mcranmer/Documents/PySR/.all-contributorsrc
Error: ENOENT: no such file or directory, open '/Users/mcranmer/README.md'
error Command failed with exit code 1.

```

indicating it looks at `$HOME` rather than `$PWD` for the `README.md` file I have indicated in my `.all-contributorsrc`.

When I try to provide the `--files` flag, it seems to trigger a different bug:
```
yarn all-contributors generate --config /Users/mcranmer/Documents/PySR/.all-contributorsrc --files /Users/mcranmer/Documents/PySR/README.md
```

```
yarn run v1.22.19
warning package.json: No license field
$ /Users/mcranmer/node_modules/.bin/all-contributors generate --config /Users/mcranmer/Documents/PySR/.all-contributorsrc --files /Users/mcranmer/Documents/PySR/README.md
