Rewrite the tests in Vitest

[GeorgeCadwallader]

Problem to solve

Currently the Conventional Tools test suite uses the oclif testing library, which makes sense since the CLI is built using oclif. However, since we are now decided that we want to move away from oclif, moving test suite provider also makes sense.

Proposal

Rewrite the tests in Vitest.

Vitest offers a lot of similar patters and concepts that other popular JavaScript frameworks do (e.g. Jest). But also includes a few other parts of functionality that we would also like to utilise.

Changed the ticket to reflect our decision to move to Vitest instead of Jest.
