SQL Trigger Template for Typescript Not Available from CLI

Hi there,

When I run `func templates list` I see "SQL Trigger" listed underneath the TypeScript Templates heading. However, when I subsequently run `func new --template "SQL Trigger" --name fooFunction` I get the following error:

> Can't find template "Sql Trigger" in "typescript"

Not the end of the world as I can see the template in this repository, but would be worthwhile to fix as it's nice to use the preset templates to initialise functions :)

Start by reproducing `func templates list` and `func new --template "SQL Trigger" --name fooFunction` for the TypeScript templates. Compare the displayed `SQL Trigger` name with the SQL Trigger template in the repository. Done means the listed name can be passed to the CLI to initialize a function without the “Can't find template” error.
