## Issue
Category cards are showing up as "odysee.com" cards in Facebook.
## Change
- `og:url` is supposed to be the canonical URL. It was hardcoded to "odysee.com", so every category was being redirected when the card is being generated.
- Removed `twitter:url`. The documentation says it will fall back to `og:url`, so there is not need to define both if it's the same.
- A side-quest from "7166 improve search metadata".
- The favicon must be from the same domain as the homepage, so the CDN URL couldn't be used, hence the additional upload.
- The favicon also needs to be multiples of 48x48 and above.
- Wanted to use SVG for the smallest size possible, but seems like Safari does not fully support it. Got Dejan to give me a reasonably-sized PNG.

## Issue
7166 improve search metadata
Depending on the search term and timing, Google extracts data from the sidebar or page content to use as the search-result description.
## Change
Defined `description` (on top of the existing `og:description` and `twitter:description`.
While I couldn't find a definitive doc saying that this is the solution, this is present in all other sites (and matches their description in a Google Search results).

## Issue
5848 Remove scroll-bar in update prompt
## Changes
- Make scrollbars appear only when necessary.
- Style the scrollbar. Similar to other areas, we skip this for Mac (can't recall why we need to skip).
## Issue
`https://github.com/lbryio/lbry-desktop/issues/6369#issuecomment-882081892`
## Changes
- Replace 'feed' with 'node-rss' for itunes spec support.
- Replace content type from 'rss+xml' to 'xml' so that the browser will display it nicely using the document tree without us having to re-format it ('node-rss' does not). Seems like all feeds that I found does it this way.
- There is no need to escape characters now that 'node-rss' does it. Nice.
## Issue
5951: OG messed up if `$"` is in title
The replacement string would contain `...$"...`. The character `$&` has special meaning in `replace`, so the output was messed up.
## Approach
Use a direct slice approach. A bit less elegant.
