PATH setting doesn't seem to be working anymore.

Description: I am using v5 of this action and the $PATH doesn't seem to be getting set. I have CLI tool that I am building and in one of my tests, I mimic running the CLI tool. Locally, I use go install then run go test ./... and since my $PATH is set, it can find the program.

For example, I have this code snippet in a test file that runs the program and some arguments:

    for _, test := range tests {
        cmd := exec.Command("poke-cli", test.args...)
        var out bytes.Buffer
        cmd.Stdout = &out
        cmd.Stderr = &out

This action used to work just fine as you can see here in previous attempts, but now, it is failing and I am not sure what happened. It first failed in this Pull Request but I didn't touch the go_test.yml file.

Here is the whole go_test.yml file:

Repro steps:
Here is a Pull Request where I am trying to run this Action and it's failing: https://github.com/digitalghost-dev/poke-cli/pull/19

Expected behavior: $PATH is set when using this action.

Actual behavior: Getting an error that the binary can't be found in $PATH:

cli_test.go:63: Unexpected error: exec: "poke-cli": executable file not found in $PATH
