Use latest cosign-installer action in goreleaser

Fix requested files parsing

Adding `git diff` parser broke `git diff --name-only` flow... This
commit allows to use both, depending on the input.

Accept `git diff` as input

This commit allows to pipe `git diff` command output into gocovsh to
display only changed portions of changed files. It might be helpful when
actively working on a feature to determine its coverage quickly, while
disregarding the rest of the code.

Use go mod proxying

This enables read build info both on binaries built by goreleaser, as
well as installed with `go install` directly.

Revert "Use Go 1.18"

This reverts commit 3de1237.

Fix line endings bug on Windows

This commit allows to properly parse package names, 
regardless of line endings (`\r\n` or `\n`) used in the 
`go.mod` file.

Add coverage percentage to files in the list

To calculate the percentage, I took the code from golang's built-in
coverage tool (html generator).
