Improve password generator with a passphrase generator

Q1. What is the problem that you are trying to solve?
There are situations where random strings are not convenient, for example if you have to type them on a physical server, or a web console where you can’t paste ( as vsphere web console). Random strings are great for machines but users are bound to make mistakes when copying them.

Q2 - Who is impacted?
Mostly sysadmins and any other users that have to type the password.

Q3 - Why is it important and/or urgent?
For those like me who use this kind of interfaces a lot in our daily jobs, passbolt would make our life easier.

Q4 - What is your proposed solution? (optional)
Similar to keepass or bitwarden, in the password generator window there can be a tab or a check button to choose passphrase generation.
There is the BIP39 specification, I think this exceeds my needs but it provides a nice word lists in some languages.
