[BUG] Cached values produced by flytekit<1.13.6 cannot be used in flytekit>=1.13.6

[eapolinario]

Describe the bug

If we use flytekit<1.13.6 and cache a value such value cannot be used if flytekit is upgraded.

For example:

from flytekit import task, workflow

@task(cache=True, cache_version="1")
def t() -> int:
    return 42

@task
def t1(x: int):
    pass

@workflow
def wf():
    t1(t())

If we run this first with flytekit<1.13.6 and then upgrade to 1.14.2 we get this error:

Expected behavior

We should be able to reuse cached values across flytekit versions.
