Tool tips network switcher

[MareenG]

Description
If your wallet does not support a network switch we display tooltips. I feel the display is not ideal especially not for mobile.
Eventhough they have different colours it feels like they are both clickable.
On Desktop the changed mouse icon indicated that the ! is not clickable but on mobile this is not obvious.

How to Reproduce
Steps to reproduce the behavior:

1. Open cowswap in mobile browser
2. Connect with MM via Wallet connect
3. Open network switcher
4. See toolips

Suggestion
It might be good to remove the ! tooltip and instead gray out the name and icon of the network.

Based on the changes in #1982 , network switcher won't be opened when a wallet does not support several networks.
The issue is no longer relevant.
