Updates Lorem Helper validation

[mikesealey]

Description

{{ Lorem }} helper will work without a number-perameter and return Lorem ipsum (equivilent to {{ lorem 11 }})

This PR makes a change to the parameter so that the validaiton understand that the number is optional

Please note: This PR contains a 1-line change, and many lint changes.

BUDI-9126 Validation text on Lorem helper incorrect

[adrinr]

This file is autogenerated, it should come from https://github.com/Budibase/handlebars-helpers
I know that is some tedious extra work, but it would be nice to change it in there and to get it being autogenerated. Otherwise, on the next "update" your changes will be lost.
This would require:

1. Update the parameter change in https://github.com/Budibase/handlebars-helpers
2. Merge it to master
3. Publish a new version (@mike12345567 can help with it)
4. On this branch, update to use the latest handlebars-helpers package and run yarn manifest from within package/string-templates
