feat: Remove time entry by id

[benthayer]

Hi, thanks for creating this repo!

I have a custom cli wrapper around AuHau/toggl-cli and it just broke for me today from the v8 to v9 migration so this is a big save for me.

I needed the remove by id functionality and it was pretty simple to add, so here's the contribution.

Thanks,
Ben

Thanks for submitting this! I'm glad you found it and its helpful. How did you find my toggl-cli?

Your PR really made my day - your PR is the first external contribution! I really appreciate it!

I'm glad I could made your day! 😄 I always love making contributions like this

I originally found the repo from your comment on this issue in the original toggl-cli and noticed that the only feature I was using that wasn't present was removing time entries by id, so I happily made my contribution and appreciate that you put in the effort to build a replica of the original tool for v9 of the Toggl API!
