Password reset documentation can be simplified (no need to install a web server to generate hashed password).

### Prerequisites

### The problem

The [Reset web password](https://github.com/AdguardTeam/AdGuardHome/wiki/Configuration#password-reset) documentation can be greatly simplified. The step 1 to install `htpasswd` is too heavy (install a web server is too heavy).

### Proposed solution

This can be done with simple linux command (which is readily available on linux machines or WSL on windows):

```bash
mkpasswd -m bcrypt -R 10
```

This will generate the bcrypt hashed string. No need to install apache2. I tested it and it worked without any problems.
