E2E test install MS -> Run MS MacOS and Linux

[loonggamma]

Context
Following the minimal need covered in this issue that implemented minimal needed e2e tests, for Windows 11.
We want to do the same for MacOS and Linux, latest versions considered as minimal scope.

List of scenarios to cover:

• As a user, I have the previous version of Massa Station installed and I download the new version of Massa Station using the landing page to install it again on my desktop.
• As a user, I have never installed Massa Station on my desktop, nor any other coding language or software, and I installed Massa Station using the landing page for the 1st time. (ie: no certificate, no port used, nothing)
• As a user, I am already using port 80 with another software and I try to installed the latest version of Massa Station using the landing page.

How to

1. For each OS, cover the scenarios above in the order of importance - the happy-path scenario is must-have
2. Make sure to include specifics scenarios per OS (Homebrew, DNSmasq installed/ not installed) - should-have
