Update npm to version 7.7.5 if needed

[apolopena]

Problem this feature will solve

This will allow #76 to be fixed.

Background

At the time of wirting this. the Gitpod platform was using npm version 6.14.11

Proposed Solution

Update npm if its current version is less than 7.7.5
Just use a spinner and update the status to Done or Failed depending of success or failure.

Constraints and Assumptions

Laravel scripts use npm
Add an API to utils.sh that can compare two version numbers that use the pattern:

• <any # of digits>.<any # of digits>.<any # of digits>

Alternatives or Workarounds

Deal with hard to track down npm errors.

Additional context

It is debatable if npm should always be updated to the latest version. I decided to just pick a known stable version and leave it there.
It definately makes it more futureproof to update to the latest version but also it could make it less stable.
