remove the about page and menu entry from top navbar

earlier crc.dev would redirect to /blog/about and that
acted as the landing page/home page, and the about.md
was a symlinkg to content/_index.md but recently on 0.123.0
release of hugo support for symlinks for input pages was removed:
gohugoio/hugo#11556

now we redirect crc.dev to crc.dev/blog and removed the about page
as the content is almost similar to the crc.dev/blog page
