Replace backslashes with slashes to fix e2e run

- What I did

Make the PWD variable on Windows a path with forward slashes (again) instead of backslashes. I saw in older workflow runs that the path used forward slashes, then started failing running the e2e tests on Windows because of it having backslashes.

I was able to reproduce locally with MinGW64 11.2.0 installed:

$ mingw32-make -f builder.Makefile e2e
mkdir -p docker-config/scan
mkdir -p docker-config/cli-plugins
cp ./bin/docker-scan_windows_amd64.exe docker-config/cli-plugins/docker-scan.exe
# TODO: gotestsum doesn't forward ldflags to go test with golang 1.15.0, so moving back to go test temporarily
SNYK_DESKTOP_VERSION=1.827.0 SNYK_USER_VERSION=1.827.0 SNYK_OLD_VERSION=1.382.1 DOCKER_CONFIG=C:\code\scan-cli-plugin/docker-config SNYK_OLD_PATH=C:\code\scan-cli-plugin/docker-config/snyk-old SNYK_USER_PATH=C:\code\scan-cli-plugin/docker-config/snyk-user SNYK_DESKTOP_PATH=C:\code\scan-cli-plugin/docker-config/snyk-desktop go test ./e2e  -ldflags="-s -w -X github.com/docker/scan-cli-plugin/internal.GitCommit=5a67dc4 -X github.com/docker/scan-cli-plugin/internal.Version=v0.1.0-231-g5a67dc4185-dirty -X github.com/docker/scan-cli-plugin/internal/provider.ImageDigest=sha256:f9291a5310e3952369eeb8cd1c2a25f0c9fc930a3ccc88e1ea20956ad86b75a4 -X github.com/docker/scan-cli-plugin/internal/provider.SnykDesktopVersion=1.827.0"
panic: open C:codescan-cli-plugin\docker-config\cli-plugins\docker-scan.exe: The system cannot find the path specified.

- How I did it

Add a subst to replace all \ with /. Surprisingly in the Makefile I didn't had to use things like double \\ backslash, just a single one is fine here.

- How to verify it

• have MinGW 64 11.2.0 installed
• Run mingw32-make -f builder.Makefile e2e that failed for me without the substitution. With this fix it only complains about missing E2E vars, but it came across the path

Should this fix the CI?

[StefanScherer]

Yes, I hope so. CI is only triggered in the upstream repo, but not in forks, that's why we don't see a status here. This PR should fix the errors we can see in the "Release and Weekly Build" workflow in https://github.com/docker/scan-cli-plugin/actions. Even if I have created this PR directly in upstream repo, we couldn't run it there, only the build-pr workflow is triggered for PR's and that runs only on Linux nodes, but not on Windows. I suggest we merge it and #204 and then see if that can build the missing linux/arm64 binary.

[StefanScherer]

Yes, CI is green again -> https://github.com/docker/scan-cli-plugin/actions/runs/2789915771

[mat007]

So we don’t have CI on the PRs? 😞

180 was trying to change that, right?

[StefanScherer]

Good catch, yes. Looking at the comments in #180 I think we should just skip the e2e test in PR's to avoid providing the env variables in PR builds from random forks.
