fix: Validate the handler function param types when registering steps.

[chengxilo]

🤔 What's changed?

It checks the step handler params while registering the steps.

⚡️ What's your motivation?

There is a FIXME tag in test_context.go file and I think I can fix it.

🏷️ What kind of change is this?

• 🏦 Refactoring/debt/DX (improvement to code design, tooling, etc. without changing behaviour)
• 🐛 Bug fix (non-breaking change which fixes a defect)

♻️ Anything particular you want feedback on?

I think we should have different error message when step registering/run because the context.Context param is in a wrong place. So probably it would be a good idea to fix it in another pr, wondering whether I should fix it in a new pr.

for example:
when there is a handler like this:

func nokInvalidParamCtxNotFirst(_ int, _ context.Context){}

Maybe we can panic with

fmt.Sprintf("%s: the data type of parameter %d context.Context should be the first param", models.ErrUnsupportedParameterType, i)
