For contributors: branch name changes in ASP.NET Core repos

[natemcmaster]

Over the coming weeks, we are planning on making the following changes to most projects in https://github.com/aspnet that are used to build ASP.NET Core.

• We will create a branch named "release/2.2". Work on this branch will be part of ASP.NET Core 2.2
• We will rename the "dev" branch to "master". This is part of aligning aspnet repos with the branch naming used by other Microsoft teams.
• We will change the default branch to "master" on GitHub.
• Update the product branding on "master" to 3.0. Work on this branch will eventually become part of ASP.NET Core 3.0

To help us prevent too much drift between release/2.2 and master, we will enable some automation to merge all changes from release/2.2 into master (3.0).
