Convert internal/fileutil, internal/tlsutil, and internal/resolver
test files from native Go testing patterns (t.Errorf, t.Fatalf,
t.Error, t.Fatal) to github.com/stretchr/testify equivalents
(assert.X, require.X).

When multiple processes try to download the same chart version
concurrently (e.g., via Terraform), they can race to write the
destination file. On Windows, this results in 'Access Denied'
errors because the file cannot be renamed while another process
has a handle to the destination.
This commit introduces 'PlatformAtomicWriteFile' to the fileutil
package. On Unix-like systems, it simply delegates to AtomicWriteFile,
maintaining existing behavior. On Windows, it coordinates writes using
a lock file (.lock). It acquires the lock, then performs the atomic
write.
Crucially, this implementation ensures that existing files are
overwritten (rather than skipped). This ensures that if a chart is
republished with the same version, the local cache is correctly updated,
preventing stale data issues.

Since Helm is going through breaking changes with Helm v4, the version path to
Helm needs to be updated.

At this time both Go 1.19 and 1.20 are supported. The version
specified in the go.mod file is the minimum version we expect Helm
to be compiled against. This is the oldest supported version to
support environments where others compile Helm. The Helm project
is using Go 1.20 to build Helm itself.
Updating to Go 1.19 also includes dealing with io/ioutil
deprecation and some additional linting issues around staticcheck.
All the staticcheck issues were in test files so linting was
skipped for those.

The directory created by `T.TempDir` is automatically removed when the
test and all its subtests complete.

* fix: write index.yaml file atomically
This refactors the already-existing `AtomicWriteFile` utility
to a central location and uses it to write index files
atomically.
This is done to avoid having half-written index files break
client requests.
Drive-bys:
- Add test for AtomicWriteFile.
- Add test IndexFile.WriteFile.
