Update dependencies to latest

[ludtkemorgan]

There are several dependencies in Detroit that have fallen behind in versions compared to what we are using in core. It is recommended to upgrade to at least the version in core if not a newer version

package	version	core version
@nestjs/schedule	1.0.2	2.1.0
@testing-library/dom	7.29.4	9.0.1
@testing-library/user-event	13.2.1	14.4.3
class-validator	0.12.2	0.14.0
Electron	13.3.0	18.3.15
Supertest	4.0.2	6.2.4

On top of that there are a couple of dependencies we could potentially remove. Node-sass and @mdx-js/loader. As part of this ticket investigate if those can be removed and if so remove them.
