[JS] isModelOnly will disable the userAgentInfo update

## Affected Component
Bump Version for userAgentInfo in XXXContext.ts

## Bug Description
changelog tool failed to bump the version for userAgentInfo in XXXContext.ts

## Impact Scope
all modular packages

## Expected Behavior
update the version

## Root Cause Analysis
for modular to update UserAgent, there's a check to check if the library is a model only library

but the check condition `src/rest/parameters.ts` will not be generated in modular

so the check is always true
