empty paths don't error in lenient mode

[Byron]

When using gix::open_opts(path, options.strict_config(false)), empty core.excludesFile values will not cause an error anymore.

Note that in strict mode, the behaviour is unchanged so invalid configuration can rather be fixed than ignored.

Fixes #1370 .

The Windows test failure is due to nextest-rs/nextest#1493 (see also rust-lang/rustup#3825). Rerunning the test should produce the same error (though I agree with doing so, just to be sure) produces the same error. It is not specific to the code in this PR, also occurring when formerly successful checks on the main branch are rerun, and locally. I have also verified, both locally and on CI, that it is also not related to any recent changes in gix-macros.

Until a proper fix is released, it should be possible to fix it by setting RUSTUP_WINDOWS_PATH_ADD_BIN=1, as in ruffle-rs/ruffle#16342. I've verified that this works locally, but I haven't yet done it on CI. I'll open a pull request here in gitoxide with that workaround shortly, so PRs such as this one can move forward until an upstream fix is available. Alternative, if you prefer to apply the change here instead, please let me know (or close my forthcoming PR if already open).

Thanks a lot for your help here - incredible how fast you figured that out, I was still puzzled.

I'd be happy to wait until your PR is merged to fix this one.

I've opened #1372 for this, adding that environment variable where needed.

Thanks! I should admit I didn't figure it out quite as fast as it might've seemed, though. Instead, the timing was fortuitous--I had already experienced the problem locally and was working on it for a short while before I saw this PR.
