Support monochrome icon for Linux system tray

[gbcox]

Steps To Reproduce

I was going to open a feature request in the community forums, but I found this:
https://community.bitwarden.com/t/add-support-for-changing-the-tray-icon-on-linux/32207/9
and it was closed with instructions to open a ticket here, so...

As you may or may not know system tray icons are now monochrome (b&w), so the current blue & white icon while attractive doesn't really fit in any more. Telegram resolved this issue by adding an option in the application settings to "Use Monochrome Icon" which fixes the issue for them. It would be nice if Bitwarden could take the same approach.

Expected Result

Add an option to use a monochrome icon if desired.

Actual Result

No option for monochrome tray icon.

Here is a photo of how telegram does it:

Here shows the current bitwarden icon in the tray. I'm also filing a but with mega-sync and insync.
