Add Netlify attribution to TRSS client page

[tellison]

The Adoptium hosted TRSS should provide attribution to Netlify for hosting it.

This can be through adding a footer to the index page. e.g.

diff --git a/test-result-summary-client/src/App.jsx b/test-result-summary-client/src/App.jsx
index 0519def..ac56b67 100644

(I don't have a TRSS developer installation to test this change)
