Content of issue for multi-line todos

[mbtools]

If a comment spans multiple lines, extend the link in the issue accordingly. It should end in Lxxx-Lyyy.

Should be easy to add by calculating the number of lines and appending the URL here:

https://github.com/alstr/todo-to-issue-action/blob/master/main.py#L117

Example Issue:

https://github.com/mbtools/TEST-Todo-to-Issue/issues/3

Change the link from https://github.com/mbtools/TEST-Todo-to-Issue/blob/13691e69ea7ca5fc58ad620ff98bdcaedb64ff73/src/ztest_todo_4.prog.abap#L5 to https://github.com/mbtools/TEST-Todo-to-Issue/blob/13691e69ea7ca5fc58ad620ff98bdcaedb64ff73/src/ztest_todo_4.prog.abap#L5-L7
