FE - Use label_name parameter in task by type API

What does this MR do and why?

In !94791 (merged) we introduce support for label_names for the task by type endpoint, this will unblock the work needed to complete #258680 (closed).

This MR adds support to the frontend for label_names. Note label_ids will be removed in #370085 (closed).

How to set up and validate locally

Creating a group level value stream

1. Ensure you have an EE license, or stub the cycle_analytics_for_groups license feature to true
2. Create a group
3. Create a project within a group (I recommend creating a project from a template such as the rails template)
4. Create a custom value stream for the new group you created
   Note: The first time you create a value stream in a group, a data aggregation needs to run, in gdk this is usually ~10mins

Seeding data for the chart

1. Seed some test VSA data

   $ VSA_SEED_PROJECT_ID=<project-id> VSA_ISSUE_COUNT=10 SEED_VSA=true FILTER=cycle_analytics rake db:seed_fu

2. Create some group labels

3. Assign labels to the newly created issues

Viewing the chart

1. Navigate to the group value stream you created
2. Open the network inspector
3. Navigate to the task by type chart (bottom of the page) adjust the filters
4. A request should be made to /analytics/type_of_work/tasks_by_type with an array of label_names as parameters
