SameSite issues in Safari Browser (reference #RM5975)

Hi Dave,

Due to SameSite security issues in Safari Browser, some of the pgadmin4
functionality isn't working (mostly the new tab functionality).

The affected Safari Browser versions (marked in red) currently tested upon
are:

1. v11.1.2
2. v12.1
3. v12.1.1
4. 13.1
5. 14.0.1

Since v12, Safari have done some security fixes, due to which this issue
has occurred. Strangely, the issue is not reproducible on v13, but
reproducible on its successor i.e. v14

Possible solutions could be:

1. Reporting this to Safari & raising an RM for tracking purposes.
2. Suggesting Safari users to make below changes in config.py or
config_distro for the work around:

*SESSION_COOKIE_SAMESITE = None*

*SESSION_COOKIE_SECURE = True*
(As we aren't going through any cross-site cookie transfer, this can be a
handy option - but still risky..)

I would suggest going with the 1st option or combination of both, but with
caution.
