Add documentation on how to actually import OPVault folder

[1010010-1-010-101-0-10-10011-1111111111]

Steps to Reproduce

1. export your 1password data in .1pif format
2. create a local vault in 1password
3. import your 1password data from the .1pif format into the local vault you created
4. go to preferences in 1password, go to sync, and choose sync to file to create an opvault file
5. open keepassxc and attempt to import the 1password info by navigating to the location of the opvault file and trying to select it -- it will not be selectable

Expected Behaviour

From step 5, you should actually be able to select the opvault and proceed to import the passwords etc, in the creation of a new keepass database .. maybe it is not working on MacOS properly ?

Actual Behavior

You cannot select the .opvault file to import the data and create new keepassxc database

Context

Remark: If you set the default app to open .opvault files as keepass, it will treat the 1password vault as a keepass database and hence still cannot open it!

Versions: KeePassXC 2.6.0 MacOS 10.15.5 Default windowing environment and desktop environment

Nevermind I found a solved duplicate issue here -- I could potentially update the KeePassXC docs to include instructions on how to find the opvault folder and how to work around the MacOS issue of treating it like a file ?

Note -- It would be super useful to have this part of the github docs and the KeePassXC website docs!

Ah someone is on it ! Only thing missing then is documentation to show how to create the opvault folder ... something arguably left out since it's 1Password responsibility to figure that out ? Could add a small tip though.
