feat: wrapping check functions in defineCachedFunction for resolving changelog info

relates to #3263

🧭 Context

For resolving changelog info I've now wrapped most of the check functions in defineCachedFunction to have the results cached and reduce fetching from the git providers.

Also added timeouts to the last fetch calls for changelogs that didn't have timeout configured.

📚 Description

Due to Gitlab making their rate limits stricter I've now wrapped most of the check functions in defineCachedFunction to have the result cached, reduce fetch calls & reduce chances of rate limits.
I've made the change for all git providers to also prevent issues with other git providers, except github with releases because ungh also caches the results and I don't want old results to be hanging around too long.

I've configured the caching for the check functions to be have maxAge at 1 hour & staleMaxAge at 30 minutes, this is to prevent having stale data being served while the endpoint cache is being renewed.

I didn't make changes for the other endpoints because they're already covered by defineCachedHandler.

I've also added timeout to the last fetch calls that changelog uses to prevent hanging when a git providers take a long time or is being overloaded.
