Checkbox Formatting Option for Markdown Reports

Follow up for lycheeverse/lychee#1623

Maybe add a new action argument, like checkbox. So you could use it like this:

- name: Run lychee
  uses: lycheeverse/lychee-action@v2
  with:
    checkbox: true

Having a way to format the results as checkboxes would be great especially in scenarios when its put into a GitHub issue

Oh yeah, I kinda forgot about that one

The --mode task option is already available in Lychee 1.18.1

The new PR should add the action option though (#279)

edit:

This should work as well.

- name: Run lychee
  uses: lycheeverse/lychee-action@v2
  with:
    lycheeVersion: v0.18.1
    args: "--mode task"
