[FE] Display data table of MRs in Merge Request Analytics

Problem

When viewing the MR Analytics page, I want to be able to view the individual MRs that are in the chart to better understand the underlying MRs that drove the trend.

Proposal

When viewing MR Analytics, show the individual merged MRs depicted in the throughput chart in a data table:

• Limit to the first 100 records, sorted by id/created_at (per #229365 (comment 382190171))
• Columns to show:
  • Date merged
  • Time to merge
  • Milestone
  • Comments
  • Commits
  • Approvals (number of approvals)
  • Pipelines (with a check if the MR passed CI when merged)
  • Line changes

Out of scope

• Sorting by column will be implemented in a follow-up: #230562
• Pagination will be implemented in a follow-up: #229842 (closed)
