Format codeowners file in a single line
What does this MR do?
The MR approval widget only recognizes 1 codeowner when there are 3. Gemnasium's MR approval widget seems to be working correctly and all the code owners are listed in a single line, see this MR.
Since @philipcunningham is currently showing up as the only code owner in the MR approval widget, and his is the last entry in the CODEOWNER file for the wildcard rule_, we think that the previous code owner with_ * rule are being ignored.
This change was originally intended to update the current 3 code owners of this project into a single line, similar to Gemnasium's CODEOWNER file, but we have opted to use a group instead.
What are the relevant issue numbers?
