feat: warn when func invoke type mismatches declared function type

[intojhanurag]

fix: #3083
This PR improves the developer experience when invoking functions with mismatched types.

Previously, if a user invoked a function with func invoke -f cloudevents while the function's func.yaml declared invoke: http, the command failed silently with a confusing error.
Now, the CLI detects this mismatch and prints a clear warning before proceeding.

Hi @intojhanurag. Thanks for your PR.

I'm waiting for a github.com member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
