Petr novota installation script fix

[PetrNovota]

when using cat some_script.sh | bash syntax, the read command does not work when not specified directly that it should read from terminal. That can be done by using read meassage < /dev/tty

@themarpe can we merge this PR? It is a simple local fix, does not affect anything else and it is critical for the linux installation to work properly on linux

Seems like my review got lost - I'm not too keen on the /dev/tty, but lets go with it for the time being

[PetrNovota]

@themarpe I have not found any other solution. I tested it on macOS as well as on linux and it looks like it works.
Do you have some other idea how to do it?

[themarpe]

No ideas on top of my head - if /dev/tty is "well defined" to be an alternate means of reading from current tty, then this is okay.
Though, this might likely fail on eg Docker installations with no tty then?

Perhaps a check would be an option, and otherwise user input would be skipped & defaults taken into account
