Migrate Bicep.MSBuild.E2eTests to use vitest

[shenglol]

• Migrated from jest to vitest
• Cleaned up ESLint dependencies and config file

The next step is to consolidate Bicep.Cli.E2eTests and Bicep.MSBuild.E2eTests into a mono workspace to further reduce the maintenance overhead of npm projects..
