[Suggestion]: Make the cypress dependency optional (does not install on FreeBSD)

[brendans-bits]

What happened?

When installing audiobookshelf >=2.10 from source, the client installation fails because cypress cannot be installed on FreeBSD.

This is a known issue in cypress

What did you expect to happen?

N/A

Steps to reproduce the issue

1. Install audiobookshelf from source on a FreeBSD system

Audiobookshelf version

= 2.10

How are you running audiobookshelf?

Built from source

What OS is your Audiobookshelf server hosted from?

Other (list in "Additional Notes" box)

If the issue is being seen in the UI, what browsers are you seeing the problem on?

None

Logs

No response

Additional Notes

I have successfully installed audiobookshelf after changing cypress to an optionalDependency in package.json

I'm happy to submit a PR for this if you feel it is appropriate.

I think it's no problem to move that to optionalDependency if you want to put in a PR for that.

Fixed in v2.12.0.
