[BUG] - POSTGRES_URL_OVERRIDE requires an unnecessary `:` in the URI

• [ ] This issue can be replicated on the demo site (https://demo.mealie.io/).

What is the issue you are experiencing?

The new POSTGRES_URL_OVERRIDE environment variable requires that a colon must be present to separate the postgres database username and password fields:

https://github.com/mealie-recipes/mealie/blob/53a1f045622da441cbd80a7e5614c62231cd8082/mealie/core/settings/db_providers.py#L55-L57

However, if one is not using a password to connect to their postgres database (for instance, if they are using peer authentication), then they should be able to omit the password and the colon altogether. See this portion of the libpq documentation:

postgresql://[userspec@][hostspec][/dbname][?paramspec]

where userspec is:

user[:password]

In my case, I set my connection string to the following in order to get mealie to connect to my database:

POSTGRES_URL_OVERRIDE="postgresql://mealie:@/mealie?host=/run/postgresql";

Yet it should be possible to provide the following instead:

POSTGRES_URL_OVERRIDE="postgresql://mealie@/mealie?host=/run/postgresql";

note the lack of : between postgresql://mealie and @.

Steps to Reproduce

1. Set DB_ENGINE=postgres and POSTGRES_URL_OVERRIDE=postgresql://mealie@/mealie?host=/run/postgresql environment variables.
2. See mealie fail to start up due to being unable to extract the password. This causes a runtime exception (instead of being handled gracefully).

Please provide relevant logs
