Add the different reconciliation types to select from

[RomySilverfin]

Is your feature request related to a problem? Please describe.

Whenever I need to change the reconciliation_type in the config file of a reconciliation text, I forget what the different types are called. So I currently have this handy.

silverfin-cli/lib/templates/reconciliationText.js

Line 26 in 7036945

"reconciliation_not_necessary",

However it would be nice to see these different options somehow, and to also throw an error if I enter a type that does not exist.

Describe the solution you'd like
Hover over reconciliation_type in config files and see the different options
Get errors when I enter non existing reconciliation types

Describe alternatives you've considered
Always have a tab open with the options in this repository.

Additional context
Mainly a grievance when building new templates!
