Update go replace versions

[kabicin]

Updates the version of packages to be replaced in go.mod and removes outdated replace commands.

These packages are no longer used as dependencies

replace (
    github.com/otiai10/copy => github.com/otiai10/copy v1.0.2
    github.com/otiai10/mint => github.com/otiai10/mint v1.3.0
)
replace github.com/docker/docker => github.com/moby/moby v0.7.3-0.20190826074503-38ab9da00309 // Required by Helm

These packages still have dependencies under the replaced version, so they have been updated to a higher version.

github.com/prometheus/client_golang => github.com/prometheus/client_golang v1.11.1
golang.org/x/text => golang.org/x/text v0.4.0
