This commit replaces `os.MkdirTemp` with `t.TempDir` in tests. The
directory created by `t.TempDir` is automatically removed when the test
and all its subtests complete.
Prior to this commit, temporary directory created using `os.MkdirTemp`
needs to be removed manually by calling `os.RemoveAll`, which is omitted
in some tests. The error handling boilerplate e.g.
defer func() {
if err := os.RemoveAll(dir); err != nil {
t.Fatal(err)
}
}
is also tedious, but `t.TempDir` handles this for us nicely.

A testing cleanup.
This pull request replaces
os.MkdirTempwitht.TempDir. We can use theT.TempDirfunction from thetestingpackage to create temporary directory. The directory created byT.TempDiris automatically removed when the test and all its subtests complete.This saves us at least 2 lines (error check, and cleanup) on every instance, or in some cases adds cleanup that we forgot.
