Can't enter commas into database configuration setup

[danielrosehill]

Bug description

When attempting to enter commas in order to limit the ability to upload data to specific database schemas only, the UI doesn't accept comma keystrokes and the comma separated value list therefore cannot be created.

How to reproduce the bug

My deployment:

Docker compose onto Linux VPS (Ubuntu)

Reproduction steps:

-> Click into database connections -> Edit a database -> Advanced options -> Limit upload permissions to specific schemas -> Attempt to upload desired schemas as comma separated values by typing names of desired schemas with separating commas
