The proper fix is in https://github.com/Byron/gitoxide/releases/tag/gix-v0.41.0
which unfortunately can't be used as it also comes with the latest `tempfile` v3.4
which causes other issues when compiling on some platforms.
Thus we first disable the flaky tests, and re-enable them with the `gix` upgrade
which should be possible once `tempfile` doesn't hinder `cargo` on some platforms
anymore.

This allows to use `gitoxide` for all fetch operations, boosting performance
for fetching the `crates.io` index by a factor of 2.2x, while being consistent
on all platforms.
For trying it, nightly builds of `cargo` can specify `-Zgitoxide=fetch`.
It's also possible to set the `__CARGO_USE_GITOXIDE_INSTEAD_OF_GIT2=1` environment
variable (value matters), which is when `-Zgitoxide=none` can be used
to use `git2` instead.
Limitations
-----------
Note that what follows are current shortcomings that will be addressed in future PRs.
- it's likely that authentication around the `ssh` protocol will work differently in practice
as it uses the `ssh` program.
- clones from `file://` based crates indices will need the `git` binary to serve the locatl repository.
- the progress bar shown when fetching doesn't work like the orgiinal, but should already feel 'faster'.
This commit is targeted at further improving the error messages
generated from git errors. For authentication errors the actual URL
fetched is now printed out as well if it's different from the original
URL. This should help handle `insteadOf` logic where SSH urls are used
instead of HTTPS urls and users can know to track that down.
Otherwise the logic about recommending `net.git-fetch-with-cli` was
tweaked a bit and moved to the same location as the rest of our error
reporting.
Note that a change piggy-backed here as well is that `Caused by:` errors
are now automatically all tabbed over a bit instead of only having the
first line tabbed over. This required a good number of tests to be
updated, but it's just an updated in renderings.
