upgrade gopkg.in/ini.v1 (#8500)

ini released v1.48.0 and deprecated the ini.AllCapsUnderscore symbol, as
such, during the upgrade we migrated to using ini.SnackCase.

-## Go Modules
-
-For historical reason, people use two different import paths for this package: `github.com/go-ini/ini` and `gopkg.in/ini.v1`. If you get error similar to the following one:
-
-```
-go: finding github.com/go-ini/ini v0.0.0-00010101000000-000000000000
-go: github.com/go-ini/ini@v0.0.0-00010101000000-000000000000: unknown revision 000000000000
-go: error loading module requirements
-```
-
-It is because one of your dependencies is using deprecated import path `github.com/go-ini/ini`, you can make a quick fix by adding the following line to your `go.mod` file (`v.1.44.0` was the latest version tagged on `master` branch):
-
-```
-replace github.com/go-ini/ini => gopkg.in/ini.v1 v1.44.0
-```
