Not able to proxy requests for assets, media files

## Information

https://whatismybrowser.com/w/MLNCGRF

## Details

# reverse proxy
location / {
proxy_pass http://127.0.0.1:3000;
proxy_set_header Host $host;
include nginxconfig.io/proxy.conf;
}

### Description

Wrong:

# reverse proxy
location / {
proxy_pass http://127.0.0.1:3000;
proxy_set_header Host $host;
include nginxconfig.io/proxy.conf;
}

Correct:

# reverse proxy
location ^~ / {
proxy_pass http://127.0.0.1:3000;
proxy_set_header Host $host;
include nginxconfig.io/proxy.conf;
}

### Steps to reproduce

Open [this link](https://www.digitalocean.com/community/tools/nginx?domains.0.php.php=false&domains.0.reverseProxy.reverseProxy=true&domains.0.routing.index=index.html&domains.0.routing.fallbackHtml=true&global.app.lang=enUS)

### Expected behavior

I expected to have `^~` after `location` directive.

# reverse proxy
location ^~ / {
proxy_pass http://127.0.0.1:3000;
proxy_set_header Host $host;
include nginxconfig.io/proxy.conf;
}

> In versions from 0.7.1 to 0.8.41, if a request matched the prefix location without the "=" and "^~" modifiers, the search also terminated and regular expressions were not checked.

### Screenshots


Start with the linked NGINX configuration generator and trace the reverse-proxy template used by its generated output. Reproduce the configuration from the provided link, then confirm that the generated reverse-proxy location includes the ^~ modifier and that the output remains valid NGINX syntax.
