As part of [min.io issue
#2136](https://github.com/miniohq/min.io/issues/2136), the crawler now
includes results from domains such as blog.min.io and resource.min.io.
By default, the search returns results from all these sources. This
update adds a filter to exclude results from domains other than
docs.min.io.
Also, added some minor CSS changes to fix the gray color palette
variables.
- Default Sphinx search page has been replaced with Algolia's
- Enabled routing to sync the search results with URL

**How to test:**
1. Click on a search result, navigate back using the browser back button
and check whether the search result modal is open and available.
2. Type a search keyword and press the enter key to navigate to the
search results page, where you can find all the results listed.
Note: You might need to start the local web server on the exact build
sub-directory to test the point number 2.
`build/[branch]/[platform]/html/` - ✔️
`build/` - ❌
- Fixed the sidebar scroll - with this fix, you'll be able to scroll to
the end of the left sidebar at any given screen height.
- Renamed content-navigation component and CSS class names for better
consistency.
- Changed the footer style by including it as part of the main content
area. This change is required to have the scroll fix mentioned at point
no. 1.
- Reduced the hero height by a small margin, in order to have more
sidebar scroll room on smaller devices such as 13 inch laptop and all.
- Used higher contrast color on search modal's bg and scrollbar thumb to
have better color consistency.
- Made scrollbar thumbs visible by default.
- Set sidebar scroll position to match the active doc item.
- Added custom scrollbars for code blocks.
