What has changed?

Small update to the white box testing glossary page (version 4.0.0):

• Title shortened to 'White Box Testing' and description rewritten as a plain definition
• Added a canonical to the combined blog guide (the same setup the black box glossary page already has)
• Added one sentence linking to the full blog guides

Reason: in Search Console (last 3 months, US) this page competes with our blog pages for 'white box testing' (896 impressions at position 21.7, 0 clicks over 3 months), while the combined blog guide ranks better for the same query (position 12.3). The page had no canonical, so it ranked as a separate page. The body content, keywords, URL, id and sidebar label are unchanged.

Type of change

• Documentation update (if none of the other choices apply).

How Has This Been Tested?

Front matter and one added paragraph in a single Markdown file. No code, component or sidebar changes.
