SQSCANGHA-55 Support GitHub self-hosted runners without wget

[antonioaversa]

Replaces wget with curl.

The base of this PR is #148, as it builds on top of it.

The PR is kept in draft to avoid accidental merging.

UPDATE: #148 has been merged, so now this PR directly targets dev.

Are we sure curl is always available? Or is it always available when wget is? If not, why not keep both, trying to use one and falling back on the other if the first one is unavailable?

Thanks for the input!

We quickly discussed it in a standup of the Mobile Squad few days ago, and decided to just replace wget with curl given its alleged larger availability, and to avoid complexifying the logic. However, while curl is available on all GitHub-hosted runners and on Docker images such as golang (base image of the user who had missing wget - tested here), we cannot be sure that curl is always available on self-hosted runners, nor when wget is.

I have made the changes to support the fallback here. They don't actually complexify the code that much and make the action more robust, so I think it makes sense to go for the fallback.

We will discuss during the standup and come back to you.

@Godin WDYT?
