- Explicitly suppress some unhandled errors
- Use "pass" credentials helper in examples, which is available
on more platforms than "secretservice" (only supporte on Linux)
- Update domain and username in examples.

Don't set Env if not set; the default is already handled if it's nil; from
the documentation: https://pkg.go.dev/os/exec@go1.20.4#Cmd.Env
// If Env is nil, the new process uses the current process's
// environment.
Use `os/exec/Cmd.Environ()` instead of `os.Environ()`, which was added in
go1.19, and handles additional environment variables, such as `PWD` on POSIX
systems, and `SYSTEMROOT` on Windows. https://pkg.go.dev/os/exec@go1.20.4#Cmd.Environ
Also remove a redundant `fmt.Sprintf()`, as we're only concatenating strings.

the "golang.org/x/sys/execabs" package was introduced to address a security
issue on Windows, and changing the default behavior of os/exec was considered
a breaking change. go1.19 applied the behavior that was previously implemented
in the execabs package;
from the release notes: https://go.dev/doc/go1.19#os-exec-path
> Command and LookPath no longer allow results from a PATH search to be found
> relative to the current directory. This removes a common source of security
> problems but may also break existing programs that depend on using, say,
> exec.Command("prog") to run a binary named prog (or, on Windows, prog.exe)
> in the current directory. See the os/exec package documentation for information
> about how best to update such programs.
>
> On Windows, Command and LookPath now respect the NoDefaultCurrentDirectoryInExePath
> environment variable, making it possible to disable the default implicit search
> of “.” in PATH lookups on Windows systems.
With those changes, we no longer need to use the execabs package, and we can
switch back to os/exec.

This is a simplification of how the docker engine implements
this feature, but it will be ported there once this is merged.
