Fixed links in installation script to use https, instead of http.

Another option is to also add -L option to curl call, making the installation follow any redirects. I opted to not do that, so that we would have broken tests when links change (if).

Checklist:

• Provided PR description.
• Tested the solution manually.
• Provided automated test coverage.
• Checked that target branch is set correctly (main for features, the oldest supported for bugs).
• Ran PHP CS Fixer for new PHP code (use $ composer fix-cs).
• Asked for a review (ping for example @ibexa/php-dev for back-end changes and/or @ibexa/javascript-dev for front-end changes).
