fix: remove footer (#1693)

## Checklist
I have:
- [ ] run the content through Grammarly
- [ ] linked to sample apps when relevant
- [ ] added the meta description for each page in the PR
- [ ] minimized the callouts and added only when necessary
- [ ] added the `queryString` parameter to the Tabs (if used)
- [ ] masked PII in images. For example, login credentials, account
details, and more
- [ ] added images only when necessary
- [ ] deleted the images that are no longer used for the updated pages
in the PR
- [ ] followed the image file naming convention while renaming or adding
new images. (Use lowercase letters, dashes between words, and be as
descriptive as possible)
- [ ] used the `<figure/>` tag instead of a markdown representation for
images
- [ ] added the `<figcaption/>` tag to add a caption to the image
- [ ] added the `alt` attribute in the `<img/>` tag
- [ ] verified and updated the cross-references or created redirect
rules for the changed or removed content
- [ ] reviewed and applied the style changes for UI formatting. For
example, Bold the UI elements(Buttons on screen) used in the doc.
