### What?
### Why?
### How?
Fixes #
-->
### What?
Updates the examples in the
[admin/metadata#root-metadata](https://payloadcms.com/docs/beta/admin/metadata#root-metadata)
and
[admin/metadata#icons](https://payloadcms.com/docs/beta/admin/metadata#icons)
sections from using `href` to `url` and fixes the way that the `images`
Type excludes the description due to `|` being parsed as column
separator
### Why?
As of right now, the examples are incorrect and the `images` type bleeds
into the description and omits it entirely
See image of table issue at `images`:

### How?
Changes to `metadata.mdx`
Fixes#8887
