Only fail webhook if http status is not 202

[isihu]

Microsoft is retiring webhooks, Workflows should be used in the future.
That also means that a webhook isn't failed when the response text is empty, but when the return code is not 202.
Due to that, the ms-teams-webhook library this action uses has released a new version, that supports the new workflows and also returns more information about the response of MS Teams.
This PR uses this response to correctly determine the success of the request.

I have not tested this thoroughly, but it works in my case.

This may be a breaking change.

O365 webhooks will be non-functional by the end of next January. Updating the library to the new version that supports workflows is going to be the only way forward for this action. Please merge this PR.

Please note that users must migrate their MessageCards here. We have not yet found a way to avoid or circumvent this.

Although we have provided a small AI tool that can help with this, we have not yet received enough feedback on the quality. Since you are one of the biggest projects on the lib, please let us know if we can still support you in any way.

I'm not the maintainer of this action, but it seems to me like the action does not use MessageCards anymore, so it should be fine right?

That is correct, but the lib also offers to send raw payloads. With the switch to sendRawAdaptiveCard this could be broken in future versions.

[isihu]

Not sure if I understood the problem correctly. Are you planning on deprecating sendRawAdaptiveCard?

[waigel]

No, it was not a blocker from me, I just wanted to point out that we will not support the sending of MessageCards via the sendRawAdaptiveCard in the future. In other words, if you switch from send to sendRawAdaptiveCard, there is a risk that it will no longer be possible to send message cards in a future version, which could be a breaking change for users with raw payload.

[isihu]

Ah, but this project should be fine as we already moved to AdaptiveCards, got it. Thanks 👍

@Skitionek any chance of having this reviewed and merged soon?
