This also removes the bold rendering of the commit message which I find quite confusing actually (too much bold text on this page):

Bundle size report 📦

Initial size	Total size	Async size	Modules
0.00% (0.00 kb)	0.01% (+0.98 kb)	0.01% (+0.98 kb)	0.00% (0)

Look at the Statoscope report for a full comparison between the commits 9694317 and 265acff or learn more.

Open explanation

• Initial size is the size of the initial bundle (the one that is loaded when you open the page)
• Total size is the size of the initial bundle + all the async loaded chunks
• Async size is the size of all the async loaded chunks
• Modules is the number of modules in the initial bundle

❌ Problem: the label i-acknowledge-this-goes-into-the-release is absent.
👉 What to do: we're in the next Sourcegraph release code freeze period. If you are 100% sure your changes should get released or provide no risk to the release, add the label your PR with i-acknowledge-this-goes-into-the-release.
