vcs repos file existence check fails on Windows

[jacobperron]

Description

I'm trying to point vcs-repo-file-url to a repos file that exists in the root of the same repository as where the action is being run. e.g.:

    vcs-repo-file-url: |
            https://raw.githubusercontent.com/ros2/ros2/dashing/ros2.repos
            "${{ github.workspace }}\ros2_java_desktop.repos"

But, curl fails since the necessary file:// prefix is not being appended by the action.

Expected Behavior

file:// is appended by the logic here:

action-ros-ci/src/action-ros-ci.ts

Lines 52 to 54 in 242ffcc

	if (fs.existsSync(vcsRepoFileUrl)) {
	return "file://" + path.resolve(vcsRepoFileUrl);
	} else {

and curl succeeds.

Actual Behavior

curl fails. For example.

To Reproduce

See example workflow in ros2-java/ros2_java#109.

System (please complete the following information)

• OS: Windows
• ROS 2 Distro: Dashing

Additional context

I'm not sure if this is user error, or a bug related to the use of fs.existsSync on Windows.

Looks like if I remove the quotation marks ("), then the action works as expected. For example:

    vcs-repo-file-url: |
            https://raw.githubusercontent.com/ros2/ros2/dashing/ros2.repos
-            "${{ github.workspace }}\ros2_java_desktop.repos"
+            ${{ github.workspace }}\ros2_java_desktop.repos

Maybe the action could be more robust to the presence of quotation marks, but seems like user-error on my part.

Edit: I'll note that the quotation marks didn't seem to be a problem on Linux.
