fix(extensions): allow consolidate@<0.16.0 to use mustache@^3.0.0

[andreyfel]

testem specifies mustache@^3.0.0 and consolidate@0.15.1 in its dependencies.
When you install testem using pnpm@7.1.0 it ends up with versions conflict:

. └─┬ ember-cli └─┬ testem └─┬ consolidate └── ✕ unmet peer mustache@^4.0.1: found 3.2.1

This is the range declared upstream, in order to change it here it needs to be changed upstream as well.

@merceyz the problem is that mustache@3 must be used with consolidate@0.15.1 and mustache@4 must be used with consolidate@^0.16.0 according to this. What is the best way to achieve that? Have a separate entry for consolidate<=0.15.1 and another one for consolidate>0.15.1?

Closing in favor of #4467

Alright, in that case the need for an upstream PR is void 👍

What is the best way to achieve that? Have a separate entry for consolidate<=0.15.1

Yes, add an entry before the current one that only targets consolidate@<0.16.0 and only specifies the mustache@3 peer dependency.

@merceyz please check if I did it correctly.
