dashboard: use "stress test" instead of "pressure test"

[yahonda]

What is changed, added or deleted? (Required)

"Pressure test" is not idiomatic English for software performance testing — in software contexts the standard term is stress test (or load test); "pressure test" primarily belongs to mechanical/physical engineering (pressure vessels, pipes). Here it reads as a literal rendering of the Chinese 压力测试, which means "stress test".

This PR renames the 5 go-ycsb pressure test occurrences to stress test, matching the "stress test" wording already used elsewhere in the docs:

• dashboard/dashboard-diagnostics-usage.md (4)
• information-schema/information-schema-metrics-summary.md (1)

Which TiDB version(s) do your changes apply to? (Required)

• master (the latest development version)
• v8.5 (TiDB 8.5 versions)
• v8.4 (TiDB 8.4 versions)
• v8.3 (TiDB 8.3 versions)
• v8.2 (TiDB 8.2 versions)
• v8.1 (TiDB 8.1 versions)
• v7.5 (TiDB 7.5 versions)
• v7.1 (TiDB 7.1 versions)
• v6.5 (TiDB 6.5 versions)

What is the related PR or file link(s)?

• Other reference link(s): companion to the Japanese i18n-ja-release-8.5 cleanup (the ja side was renamed 圧力テスト → 負荷テスト).
