Fix pipeline for 202305 branch

[ganglyu]

Why I did it

axw gocov was modified to use go 1.22 while currently sonic-gnmi still uses 1.13 a few days ago from this PR creation date. To ensure pipeline still works, we are specifying last stable version of axw gocov that still worked with sonic-gnmi pipeline which was 1.1.0

How I did it

Specify gocov version
