Remove duplicate workflows directory

[jhamon]

Problem

The workflows/ directory is duplicating files in the .github/workflows directory, but these files don't actually have any effect in github actions.

Solution

Delete duplicate files.

Type of Change

• [x] None of the above: Cleanup/refactoring

Test Plan

Observe github actions still run on this branch even after these duplicate workflow files are removed.

@jhamon will review both PRs today. Sorry, hadn't had a chance yet 😬

Landed this without passing tests because I didn't change any product code so I know the failing integration tests is unrelated.
