Mask hosts with port properly

## Describe the bug

Hosts with the ports are not masked properly.

Add a secret `HOST_PORT = 1.1.1.1:22` and in the logs you will see the host IP address - `1.1.1.1:`. Make sure to add a working configuration, because IP is shown only when `script` is executed.

## Yaml Config

```yaml
name: remote ssh command
on: [push]
jobs:
build:
name: Build
runs-on: ubuntu-latest
steps:
- name: executing remote ssh commands using password
uses: appleboy/ssh-action@v1
with:
host: ${{ secrets.HOST_PORT }}
username: ${{ secrets.USERNAME }}
password: ${{ secrets.PASSWORD }}
script: "echo I\'m; whoami; echo on; hostname"
```

## Related environment

One of the workaround is to add one more `HOST_MASKED=1.1.1.1` secret with the just IP, to mask it.

Also, it would be very useful to improve existing masking and make it more user friendly
```diff
- ***: I'm user on hostname-1
- ***: I'm user on hostname-2
+ HOST-1: I'm user on hostname-1
+ HOST-2: I'm user on hostname-2
```

When you have multiple hosts and they are all masked, it is not clear on which one which output did we get.
