👷 [e2e] group ignored browser log tags by matched pattern

[thomas-lebeau]

Motivation

When E2E tests encounter ignored console log messages (e.g. "Layout was forced before the page was fully loaded."), they add a test.fixme tag to flag them. The tag was including the full log.message, which contains dynamic content like {file: "http://172.28.56.32:9324/datadog-rum.js" line: 1}. This made each occurrence unique, preventing proper grouping in test reporting.

Changes

Use the matched ignore pattern as the test.fixme tag value instead of the full log message. This ensures all occurrences of the same warning type are grouped together.

Test instructions

No functional change — just affects how the test.fixme tag value is reported.
