Improve reverse-proxy document and fix nginx config bug (#24616)

Close #23711, thanks to @ghnp5 !
Close  #24612, thanks to @DanielGibson !

Major changes:

* the default value of nginx's client_max_body_size is too small, so put
a 512M here
* move `Resolving Error: 413 Request Entity Too Large` to a sub-section
of `Nginx` section
* make nginx use unescaped the URI and keep "%2F" as is when using
sub-path
* add details for General sub-path configuration

### Resolving Error: 413 Request Entity Too Large
This error indicates nginx is configured to restrict the file upload size,
it affects attachment uploading, form posting, package uploading and LFS pushing, etc.
You can fine tune the `client_max_body_size` option according to [nginx document](http://nginx.org/en/docs/http/ngx_http_core_module.html#client_max_body_size).
## Nginx with a sub-path
In case you already have a site, and you want Gitea to share the domain name, you can setup Nginx to serve Gitea under a sub-path by adding the following `server` section inside the `http` section of `nginx.conf`:
```apacheconf
```
server {
listen 80;
server_name git.example.com;
# Note: Trailing slash
location /git/ {
# Note: Trailing slash
proxy_pass http://localhost:3000/;

## Resolving Error: 413 Request Entity Too Large
This error indicates nginx is configured to restrict the file upload size.
In your nginx config file containing your Gitea proxy directive, find the `location { ... }` block for Gitea and add the line
`client_max_body_size 16M;` to set this limit to 16 megabytes or any other number of choice.
If you use Git LFS, this will also limit the size of the largest file you will be able to push.
## Apache HTTPD
If you want Apache HTTPD to serve your Gitea instance, you can add the following to your Apache HTTPD configuration (usually located at `/etc/apache2/httpd.conf` in Ubuntu):

This config assumes that you are handling HTTPS on the traefik side and using HTTP between Gitea and traefik.
Then you **MUST** set something like `[server] ROOT_URL = http://example.com/gitea/` correctly in your configuration.
## General sub-path configuration
Usually it's not recommended to put Gitea in a sub-path, it's not widely used and may have some issues in rare cases.
If you really need to do so, to make Gitea works with sub-path (eg: `http://example.com/gitea/`), here are the requirements:
1. Set `[server] ROOT_URL = http://example.com/gitea/` in your `app.ini` file.
2. Make the reverse-proxy pass `http://example.com/gitea/foo` to `http://gitea-server:3000/foo`.
3. Make sure the reverse-proxy not decode the URI, the request `http://example.com/gitea/a%2Fb` should be passed as `http://gitea-server:3000/a%2Fb`.
