feat: github action to check if PR has requested labels before being merged

[gauthierpetetin]

Description

The purpose of this new Github action is to check if PRs have the requested labels before they get merged:

• A team label, i.e. a label starting with team- string (or external-contributor label)
• A QA label, i.e. either QA Passed or No QA Needed/E2E Only or Spot Check on the Release Build?

Furthermore, it forbids merging PRs with the following labels: needs-qa, QA'd but questions, issues-found, need-ux-ds-review, blocked, stale, DO-NOT-MERGE. A consequence is that we can get rid of this github action.

Hi @cortisiko and @sethkfman ,
I'm not sure how to proceed with this PR, as @sethkfman mentioned last Friday, that enforcing the addition of a QA label on every PR might introduce a habit where contributors rely on Core Mobile QA team when contributing to Mobile code base, while we want to progressively get away from this.
@cortisiko what do you think?
Does it make sense if I update this PR such that it:

• Forces the addition of a team label, i.e. a label starting with team- string (or external-contributor label)
• Forces the addition of QA label, i.e. either QA Passed or No QA Needed/E2E Only or Spot Check on the Release Build
• Forbids PR to be merged if they have the following labels: needs-qa, QA'd but questions, issues-found.

@cortisiko @sethkfman, here's a new proposal, where I removed the QA label check in this commit.

[cortisiko]

@gauthierpetetin Using QA labels on PRs is not limited to the mobile core team; all teams utilize these labels to communicate the type of testing conducted or needed during release testing to the QA engineer. The QA labels help guide us during release testing. We identify based on the label applied to a PR what level of testing is needed during releases. However, if we decide to stop using QA-specific labels, we should have an alternative labeling system to inform the release QA engineers about whether testing has been performed or not. Ideally, engineers would apply this label once testing has been done. For instance, we can use labels to indicate if testing has been completed (automated and or manual), or if the PR doesn't require any testing, such as for documentation or unit test changes.

Anyways what you proposed is fine. We will iron out the details on the proper label soon.

As discussed with @danjm @sethkfman @cortisiko @PeterYinusa @vpintorico last Friday, I updated this PR to:

• add checks for these labels in this new Github action: need-ux-ds-review, blocked, stale, DO-NOT-MERGE
• remove the old DONOTMERGE github action as duplicate of this new Github action

Here's the corresponding commit.

Looks good to me. Added only an error message improvement suggestion.
