trying to run `ls-tree` (using `raw`) fails when using wildcards

[ATGardner]

i am trying to run this code snipper:

...
const git = simpleGit(dir, config).env(COMMON_ENV_VARS)
const res = await git.raw('ls-tree', '-r', '--name-only', ref, '--', 'README.m?')

and the res is empty ('').
when i manually run the same command (git ls-tree -r --name-only main -- README.m?), i get the correct response (README.md)

i followed down the rabbit hole of using raw, and it seems like the issue is the usage of spawn. it tries to resolve the wildcards before the call, instead of sending them as-is into the process. adding a spawn option of shell: true resolves this. but currently, the package only allows sending in uid and gid.

i will create a pr that exposes the shell field of SpanOptions as well. i hope it gets merged.
