Improvements for the readme about docker-rclone

[wiserain]

1.

It should state:
"...you have to specify one local directory"
Otherwise the script doesn't appear to call Mergerfs, both have to have values.

I believe it is already in the README like below.

..., it is meaningful only when you mount an additional /local directory.

2.

And this seems to be incorrect too: RCLONE_REMOTE_PATH=remote_name:path/to/mount

Should be: RCLONE_REMOTE_PATH=remote_name: The /path/to/mount is hardcoded as /cloud which can be defined in the docker-compose as - /path/to/mount:/cloud

It is entirely up to the user. When you want a subpath to be mounted, you can use path/to/mount, which will execute mount command like rclone mount remote_name:path/to/mount /cloud. Also you can omit path/to/mount to make it short.

3.

And these two: COPY_LOCAL_SCHEDULE MOVE_LOCAL_SCHEDULE

Should be: COPY_LOCAL_CRON MOVE_LOCAL_CRON

Thank you. Will be fixed soon.

4.

I also found that MOVE_LOCAL_AFTER_DAYS has to be set to any number for the move script to work, I don't understand the code well but I think the MOVE_LOCAL_EXCEEDS_GB has a null value check but MOVE_LOCAL_AFTER_DAYS doesn't and so it errors. Or it could be defaulted to a sensible number like 5 the same way as the GUID and PGID are.

I will also take a look. Thanks.

Regarding MOVE_LOCAL_AFTER_DAYS, it has a null check as MOVE_LOCAL_EXCEEDS_GB and MOVE_LOCAL_FREEUP_GB do. Would be helpful if you could share the error message.
