install.sh-script is using bash specifics while using sh in the hashbang

Updating vim-doge today on my computer led to the following errors

> ./scripts/install.sh
./scripts/install.sh: 17: [[: not found
/usr/bin/curl
./scripts/install.sh: 24: [[: not found
./scripts/install.sh: 31: [[: not found
./scripts/install.sh: 33: [[: not found
vim-doge does not support Windows yet

I am on Ubuntu here. I think the problem is related to sh being linked to dash on this computer, whereas the script used bash-extensions that dash does not support. I would suggest to either change the first line of the script to #!/usr/bin/env bash, or not use [[ in the script.

To Reproduce

Executing the script on a linux system that differentiates between sh and bash will lead to an error.

That's a problem that happened due to the merge from yesterday. We decided to use sh as it's installed on almost every system. We can't guarantee bash is installed in all systems. I'll make it compatible with dash.

@kkoomen - fix does not affect line 33 elif [[ $OS == 'Linux' ]]; then which still gives error. Please fix that line, too.
