How to send photo as link

Hello!
I want to send a picture generated by api, but the bot just skips the code section with sending a photo if I specify a link ((
I tried to specify the link both in quotes and without

Example code:
```yml
name: telegram message
on: [workflow_dispatch]
jobs:

build:
name: Build
runs-on: ubuntu-latest
steps:
- name: send default message
uses: appleboy/telegram-action@master
with:
to: ${{ secrets.TELEGRAM_TO }}
token: ${{ secrets.TELEGRAM_TOKEN }}
message: hello
photo: https://cataas.com/cat
```

Start with the example workflow in the issue and inspect how the action handles its photo input and external URLs. Reproduce the workflow with https://cataas.com/cat, then verify that the photo is sent instead of being skipped and document or test the resulting behavior.
