Fix missing VSA request parameters

What does this MR do?

In !40826 (merged) we updated the request parameters for various VSA api requests to take an object instead of a list of parameters. This MR:

• Updates the parameter name
• Adds additional specs to ensure filters are applied

Steps to reproduce

1. Navigate to VSA for a group ie. https://gitlab.com/groups/gitlab-org/-/analytics/value_stream_analytics
2. Select a new start date, for example 2020-05-01
3. The data in the stage table and charts should be updated
4. The api requests will include the updated filter values
