increase default SecretsCmdTimeout

[tehut]

#27618 prompted me to share a small design memo around implementing the configuration options proposed in our internal CPI RFC (NMD-02). The decision to increase the default timeout instead of implementing configuration was an option that grew out of our discussion of that memo.

This PR just increases the default time from 10s -> 60s.

Suggested change

	secrets: increase timeout
	secrets: increase plugin execution timeout from 10 to 60 seconds

we have some inconsistency about present-vs-past tense (like "increased") or Capitalization in these things, but a bit more info is helpful for folks who read this later without context

[tehut]

makes sense, I think I was doing some weird security by obscurity thing. Not really reasonable on an open source project 🤦

LGTM!
