Update all DncEng azure functions to runtime >= 4.x

[MattGal]

To update, by subscription:

DotNet Engineering Services:

• [ ] commenttriggers (unknown repo)

Helix

• [x] helix-autoscale-prod (dotnet-helix-machines repo)
• [ ] rollout-scorer-prod (arcade-services repo)

These four are for sleet feeds for 2.1 builds; Since this requirement doesn't matter til December and ostensibly the last 2.1 build is in August 2022, we should probably not

• [ ] dotnetclimsrc
• [ ] dotnetfeedmsrc
• [ ] transport-feed-proxy
• [ ] dotnet-feed-internal

HelixStaging

• [x] helix-autoscale-int (dotnet-helix-machines repo)
• [ ] rollout-scorer-int (arcade-services repo)

Unassigned myself and moved out the date, as we have a clean to-do list here and completion by 11/1/2022 would be more than enough advance time to have no downtime or problems.

Comment Triggers is not in use (and has no source code), rollout-scorer is already done, and the sleet feeds are unlikely to ever be updated. As such, I will clean up comment triggers and close this.
