Label when *all* reviewers have approved

[hugovk]

On our project, when an author creates a PR, they choose how many people to review their PR. It's usually 2 people, but sometimes 1, sometimes up to 6.

Rather than labelling when a fixed number have approved (eg. APPROVALS: "2"), would it be possible to label once all the current PR's reviewers have reviewed?

For example:

• if a PR has 2 reviewers, label when both have reviewed
• if a PR has 4 reviewers, label when all 4 have reviewed
• if a PR has 8 reviewers, label when all 8 have reviewed

Perhaps allow something like APPROVALS: "all" in the workflow .yml, and then something like this (pseudocode):

if [[ "$APPROVALS" == "all" ]]; then
    $APPROVALS = length($reviews)
fi

and do it somewhere before this:
