[SPIKE] - Parallelize Cypress runs

[fzhao99]

Description

Once our e2e isolation effort is done / each of the e2e's can run individually, we should look into parallelizing our Cypress runs to take advantage / make our CI ⚡blazing fast⚡

Proposed solution

Research options for us to parallelize our Cypress runs. Considerations include

• Resource constraints in our Github runners?
• Leveraging the cached image infra that the devops team did for the testing workflow refactor
• Whether we can use Cypress Cloud / other out of box Cypress solutions or need something else

Additional context

• Cypress Parallelization docs
• This should be a solved problem, so might want to do some analysis on options out there other teams use
