Switch to `ember-cli-htmlbars`

[bmish]

Switch from deprecated package to replacement.

ember-cli-htmlbars-inline-precompile Deprecated Usage of this project is deprecated, its functionality has been migrated into ember-cli-htmlbars directly. Please upgrade to [email protected] or higher.

Note: @types/htmlbars-inline-precompile is still present and I haven't touched that as I don't think there's a renamed/replacement package for its types (yet).
