feat: GetAppDetails function in templates/triggers

[paydaycay]

Hi ! I suggest this PR to add function repo.GetAppDetails to templates/triggers to support loading application details.

Hope the code is clear enough because it's my first time in golang

Hi @alexmt I fixed the problem with the tests (sorry I didn't write test but I'm not comfortable enough with golang to write tests) but I don't know how to resolve the problem with golangci-lint.
Someone already encountered the problem but I don't know if we are in same case.
Could you help me to fix this ?

That looks very solid for a first contribution! Thank you @paydaycay ! looking

Awesome! I have no comments for code, just formatting nitpicks.

Can you please run this command to sort imports:

find . -name \*.go | xargs -I {} goimports -w {} 

and one more to regenerate mocks

make generate
