Escape backslashes from the paths in the generated code

This is required for the library to work on Windows.

Otherwise, it would fail with errors like:

[error] 2 |object Snapshots extends com.indoorvivants.snapshots.Snapshots(location = "D:\Projects\cue4s\modules\cats-effect\src\snapshots\catsEffectJS", tmpLocation = "D:\Projects\cue4s\modules\cats-effect\target\js-3\resource_managed\test\snapshots-tmp", forceOverwrite = false)
[error]   |                                                                                             ^
[error]   |                                                  invalid escape character

Thanks, Windows strikes again :D

Are there no APIs on windows JVM that produce a good string out of File/Path? That's a shame.

As part of this, do you think it's possible to turn the build into a matrix build (here: https://github.com/indoorvivants/snapshot-testing/blob/main/.github/workflows/ci.yml#L13) running on windows as well?

Frankly I completely missed this being a problem

Yeah, I think this is a particularly hairy case, because the String is technically correct, but needs to be "double escaped", as it's pasted straight into the code.
I know that there's a escapedString function but:

• It's private
• It's Scala 3 only

I think so, and I imagine it's quite easy, but I think it might be easier for you to do it (feel free to push commits to this PR).
I am not able to trigger the workflow without pinging you (see the screenshot), so I have no easy way to check if I messed something up 🙃

Welp, I tried to add windows: https://github.com/indoorvivants/snapshot-testing/actions/runs/12115271668/job/33773314295#step:4:602

The resulting error looks worse than what I have motivation for right now..
