[docs] Revamp the installation guide (#1877)

This tries to revamp/restructure the installation guide. It's renamed to
"Getting Started" as it now contains a few more things than just the
installation, especially the deployment considerations which we didn't
use to spell out as much ahead of time.

Installation is now a section with the guides on their own. I've removed
a bit of redundancy like the user creation. I also removed the rogue
reverse proxy section in the Docker guide and lifted that into the
reverse proxy section.

-# WebSocket
-
-GoToSocial uses the secure [WebSocket protocol](https://en.wikipedia.org/wiki/WebSocket) (aka `wss`) to allow for streaming updates of statuses and notifications via client apps like Semaphore.
-
-In order to use this functionality, you need to ensure that whatever proxy you've configured GoToSocial to run behind allows WebSocket connections through.
-
-The WebSocket endpoint is located at `wss://example.org/api/v1/streaming` where `example.org` is the hostname of your GoToSocial instance.
-
-The WebSocket endpoint uses the same port as configured in the `port` section of your [general config](../configuration/general.md).
-
-Typical WebSocket **request** headers as sent by Pinafore look like the following:
-
-```text
-Host: example.org
-User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:99.0) Gecko/20100101 Firefox/99.0
-Accept: */*
-Accept-Language: en-US,en;q=0.5
-Accept-Encoding: gzip, deflate, br
-Sec-WebSocket-Version: 13
-Origin: https://pinafore.social
-Sec-WebSocket-Protocol: null
-Sec-WebSocket-Extensions: permessage-deflate
-Sec-WebSocket-Key: YWFhYWFhYm9vYmllcwo=
-DNT: 1
-Connection: keep-alive, Upgrade
-Sec-Fetch-Dest: websocket
-Sec-Fetch-Mode: websocket
-Sec-Fetch-Site: cross-site
-Pragma: no-cache
-Cache-Control: no-cache
-Upgrade: websocket
-```
-
-Typical WebSocket **response** headers as returned by GoToSocial look like the following:
-
-```text
-HTTP/1.1 101 Switching Protocols
-Upgrade: websocket
-Connection: Upgrade
-Sec-WebSocket-Accept: WVdGaFlXRmhZbTl2WW1sbGN3bz0K
-```
-
-Whatever your setup, you need to ensure that these headers are allowed through your proxy, which may require extra configuration depending on the exact proxy being used.
