Create GitHub team for reviewing src (C++) changes

We currently don't have a team that we can ping for C++ changes that don't require familiarity with a particular subsystem. Subsystem teams such as @nodejs/crypto have very few active members who frequently review C++ changes, so pinging these teams is not always helpful.

I'm proposing to create a new team under @nodejs/core, maybe @nodejs/cpp-reviewers, to address this.

To not start with an empty team, I'd like to add a small subset of active collaborators based on some git statistics, e.g., number of authored/reviewed commits that change src/* within the last year or so.

(I was going to create this in the core repo but I don't know how to bypass the templates there.)

This has been open for more than a week with a few +1s and no objections, so I created the team as proposed.

@nodejs/cpp-reviewers You have been added to this team because at least one of the following is true, based on the commit history from the last 365 days:

1. You reviewed at least 5 commits, and at least 50 % of all commits that you reviewed modified files in src/.

   join -t $'\t' -1 2 -2 2 <(git log --format='format:%b' --since '1 year ago' | grep '^Reviewed-By: ' | tr -d '\r' | sort | uniq -c | awk '{ f=$1; $1=""; print f"\t"$0; }') <(git log --format='format:%b' --since '1 year ago' -- src | grep '^Reviewed-By: ' | tr -d '\r' | sort | uniq -c | awk '{ f=$1; $1=""; print f"\t"$0; }') | awk  -F'\t' 'BEGIN {OFS = FS} { r=100*$3/$2 ; if ($2 >= 5 && r > 50) { print $1 } }'

2. You authored at least 15 commits that modified files in src/.

   git log --format='format:%aN' --since '1 year ago' -- src | sort | uniq -c | sort -nr | awk '{ if ($1 >= 15) print $0 }'

3. You are among the 5 collaborators who reviewed the most commits that modified files in src/.

   git log --format='format:%b' --since '1 year ago' -- src | grep '^Reviewed-By: ' | tr -d '\r' | sort | uniq -c | sort -nr | head -5

Please feel free to remove yourself from the team if you do not wish to be pinged for reviews.

Everyone else, please feel free to add yourself to the team if you do wish to be pinged for reviews.
