Update index.ts

[bombjackit]

Description, Motivation, and Context

In _getAllTemplates changed try catch with .catch on first call to template.getTemplate, because template.getTemplate is a promise, with externally try catch the error is not catched.

If you use this node in node-red (for example using node-red-contrib-cip-st-ethernet-ip), node-red crash with Uncaught Exception

How Has This Been Tested?

I try this commit with my test environment (I have some rockwell plc that I read from like 1756-L82ES and 1756-L81ES)

• Node.js 18.19.0
• Node-red 3.1.3
• Windows 11 x64
• node-red-contrib-cip-st-ethernet-ip 2.0.2

This commit works in case of #21 : I think that try catch is inserted to resolve this issue.
