page feedback: "Ask AI" widget covers footer buttons

### URL https://opentelemetry.io/ ### Description When I scroll to the bottom of the page, there is a line of hyperlink icons at the left side of the page footer and another at the right. However, the "Ask AI" widget that floats near the bottom right corner of the Web browser obscures the last two hyperlinks "Marketing Guidelines" and "Site Build Info" almost entirely. <img width="1347" height="795" alt="Screen shot of opentelemetry.io web page, with Ask AI widget in front of clickable links" src="https://github.com/user-attachments/assets/e5a9c4b3-1b52-4c95-bce9-1213e210c96d" /> Possible ways to fix this: 1. Move the right-side line of icons a bit to the left, to reserve space for the "Ask AI" widget. 2. Add more padding to the bottom of the footer, so that the icons can be scrolled above the "Ask AI" widget. 3. Make the "Ask AI" widget move higher up when the page is scrolled all the way to the footer. 4. Let the user drag the "Ask AI" widget out of the way. Mockup for 1: <img width="1347" height="795" alt="Screen shot of opentelemetry.io web page, edited to move the clickable links aside so the Ask AI widget does not cover them" src="https://github.com/user-attachments/assets/e3bd4ad2-9112-402b-b516-cd4746ccbc7b" /> Mockup for 2: <img width="1347" height="795" alt="Screen shot of opentelemetry.io web page, edited to allow scrolling the clickable buttons higher up so the Ask AI widget does not cover them" src="https://github.com/user-attachments/assets/e1e1a31d-53b2-4dca-a2a1-e4b5dfb62625" /> Caused by <https://github.com/open-telemetry/opentelemetry.io/pull/9651>, I guess. And related to <https://github.com/open-telemetry/opentelemetry.io/issues/9662>.
