Commit History not being preserved from initial migration

I am migrating a service from monorepo to it's own repo, for initial copying the files from source repo to destination repo, git commit history of source repo is not being copied over.

Config looks like

```
core.workflow(
name = "abc_monorepo",
mode="ITERATIVE",
origin = git.origin(
url = "https://github.xyz.net/abc/ghi.git",
ref = "main",
first_parent = False,
),
destination = git.destination(
url = destinationURL,
fetch = "main",
push = "main",
),
origin_files = glob([
"mno/**"
],
exclude = []),
transformations = [],
destination_files = glob(
["**"],
exclude = []
),
authoring = authoring.pass_thru("ghi "),
)
```
