fix: Remove second `uses` in example

[sarina]

What this PR does / Why we need it

Removes the first uses clause from the example Action code.

GitHub Actions only allows one uses clause, otherwise error 'uses' is already defined will appear.

You only need to call this action by invoking the action fro this repo, you do not additionally need to invoke actions/checkout@v2

Which issue(s) this PR fixes

It's possible that #333's complaint is resolved by this, but I don't know.

@sarina Thank you for your contribution! As far as I know, you can use multiple uses clauses in steps. Can I see your workflow file?

the commit that added the double uses line: https://github.com/openedx/tcril-engineering/commit/ce592eb449b87687700375991df476789ac701ac resulted on this workflow failure on the commit ce592eb:

This is the change I made that resolved the above Actions error: https://github.com/openedx/tcril-engineering/commit/1392dff234aec0ab3ef8d7d8346597639c085c6b note action run on commit 1392dff

This is the workflow that we currently have working: https://github.com/openedx/tcril-engineering/blob/main/.github/workflows/add-GHrequest-to-team-board.yml

it may just be syntax? there's a few examples of multiple uses clauses here: https://docs.github.com/en/actions/learn-github-actions/contexts but none of them are in the

steps:
  - name:
    uses:
    uses:

syntax . Regardless without the uses: actions/checkout@v2 it still works. I've never had to use the checkout action to to grab another action.

@aximov - I have been playing with additional Actions this morning and wherever I look, I see the checkout action being performed separately as part of the first in a series of job steps. See https://github.blog/2021-03-04-4-things-you-didnt-know-you-could-do-with-github-actions/ for an example of one job with multiple steps, each doing something specific - checkout, then npm, then dependency install, etc. I think it may be better to change this PR to not remove the checkout action entirely but rather put into its own step.

Hi! This one has been open awhile. Any thoughts on my above response?

I also emphatically disagree that you can have two uses: clauses. Did you look at the error in my PR description? It literally says 'uses' is already defined

[sarina]

Thanks! And thank you for creating and maintaining the action.

I apologize for the extremely late response. I'm glad that you and I have ultimately reached the same understanding regarding the workflow syntax. Thank you for creating this pull request. It will make the README more understandable.
