Maintenance: migrate test runner to vitest for parser package

[dreamorosi]

Summary

To continue the migration from Jest to Vitest we need to move over the tests for the parser package to use the new test runner.

In doing so, we can also take the opportunity to streamline the test setup by avoiding loading all events for each test file/case, and remove unused/redundant test cases/events.

Why is this needed?

So that we can continue the migration as well as improve the overall performance and correctness of the tests, which currently rely on heavy I/O and might contain flawed assumptions/tests.

Which area does this relate to?

Parser

Solution
