### What?
This PR fixes numerous links across the docs, both internal docs links
and external links. This PR also fixes some minor formatting issues in
some places, as well as optically aligns the markdown tables in tables
that had broken links.
### Why?
To properly link readers to the correct location in the docs, and for
better formatting and easier consumption.
### How?
Changes to many `.mdx` files in the `docs` folder.
Notes:
- There are duplicative section id's in `docs/authentication/email.mdx`,
I've fixed one such link, but have left it as is for now.
### What?
Fixes a link to the `storage-uploadthing` adapter in Github.
### Why?
To link readers to the correct package location.
### How?
Change to `docs/upload/storage-adapters.mdx`.
Credit to rik in Discord for the catch.
### What?
Adds custom anchor tags to docs where duplicate headings exist.
### Why?
Anchor links would not correctly navigate to the proper point on the
page if there were multiple headings with the same string.
### How?
The website now supports adding custom `#anchor` to a heading in
markdown that will attach to the headings and table of content list
items. This PR adds custom anchors to the docs that have duplicate
headings.
**Example:**
```md
/docs/upload/storage-adapters.mdx
### Usage#vercel-blob-installation
```
Generates the path:
`/docs/upload/storage-adapters#vercel-blob-installation`
**BREAKING:**
Improves type-safety of collection / global slugs by using `CollectionSlug` / `UploadCollectionSlug` and `GlobalSlug` types instead of `string` in these places:
Adds `UploadCollectionSlug` and `TypedUploadCollection` utility types
This also changes how we suggest to add an upload collection to a cloud-storage adapter:
Before:
```ts
azureStorage({
collections: {
[Media.slug]: true,
},
})
```
After:
```ts
azureStorage({
collections: {
media: true,
},
})
```
### What?
I noticed a spelling error in the banner of the beta docs and decided I
could save everyone some time by *running the entirety of the beta docs*
through a spellchecker.
### Why?
To fix many spelling and formatting mistakes at once.
### How?
By enabling `edit mode` in my browser and letting the built-in
spellchecker perform its magic (and changing _only_ where it made
sense).
~~Ironically, the original spelling mistake that inspired me to do this
remains unchanged as that is a part of the website repo. [PR for that is
here](https://github.com/payloadcms/website/pull/388).~~
Example:
```sh
pnpm add @payloadcms/plugin-sentry
```
to:
```sh
pnpm add @payloadcms/plugin-sentry@beta
```
Because of this, people can be confused with the wrong installed
version. We'll change it back on stable
