Update utils.bash to use the new release URL format

[pedropombeiro]

This change adapts the script to the new URL format of the viddy releases:

Scenario	URL
Before	https://github.com/sachaos/viddy/releases/download/v1.1.2/viddy_Linux_x86_64.tar.gz
After	https://github.com/sachaos/viddy/releases/download/v1.1.2/viddy-v1.1.2-linux-x86_64.tar.gz

From personal experience, this will break old versions and folks still depend on those old versions even if while they might get the updated plugin.

I suggest adding a semver comparison and toggling the new/old URL based on the version where the change happened. There's even a commonly used verlte function in use in a number of asdf plugins. Here's an example in one of my plugins: https://github.com/elementalvoid/asdf-nova/blob/master/bin/install#L38 (and the function in utils.sh).

I don't believe this would work for macs as those downloads now use macos as opposed to darwin. See #9

Good point. I've improved the script to work on macos too:

It would be nice to have it merged as we cannot install the viddy now

@ryodocx thank you very much, tested, everything works as expected, was able to install 1.2.0 version using asdf and default plugin repo
