[docs] Document improved metrics chart filter tag rendering

[aspire-repo-bot]

Documents changes from microsoft/aspire#18382 by @JamesNK.

Targeting release/13.5 based on the source PR milestone 13.5 (exact match on microsoft/aspire.dev).

Why this PR is needed

microsoft/aspire#18382 changed how dimension tag values are displayed in the metrics chart filter panel. Previously all values were rendered into the DOM, which could cause a browser reflow long enough to kill the SignalR connection when a dimension had hundreds of values. The fix introduces two user-visible behaviors:

1. Tag value ordering: Values are now ordered numerically when all values parse as numbers, or alphabetically otherwise.
2. 20-value inline cap with overflow badge: Only the first 20 ordered values are rendered inline; any additional values are shown as a +N count badge. Selecting the badge opens a popover with the full list.

Neither behavior was previously documented.

Changes made

• Updated src/frontend/src/content/docs/dashboard/explore.mdx — Added description of tag value ordering and the 20-value inline cap with +N overflow badge, immediately after the existing filter screenshot.
• Updated src/frontend/src/content/docs/whats-new/aspire-13-5.mdx — Added a bullet to the "Dashboard and telemetry improvements" section covering the same improvement.
