test(flattenObject): change using constant date in test case

[choi2021]

I have made a PR regarding the take(compat) function, but it failed due to issues in the flattenObject test case.

The failure was caused by different date objects being used for comparison in the test cases.

To fix this, I have modified the test cases to use a consistent date object for comparisons, ensuring that the date objects being compared are identical.

This looks good to me.

There are a couple code formatting issues. This could be fixed by running Prettier on the whole file (yarn prettier --write src/object/flattenObject.spec.ts), but that would create a larger diff because the file has mixed formatting currently.

PS: I approved this PR even though I’m not a maintainer. I’m not sure what this project's policy is for review by non-maintainers. Is it fine to approve, or better to just comment?
