pbts generates incorrect .ts.d file for fields with 'prototype' in their name

[mdouglass]

protobuf.js version: 6.8.5

Using the proto file (see attached, it contains a single message with a field called prototypes_url), run the following commands to generate a .d.ts file. The generated test.d.ts (see attached) contains an interface with the field name prototypesUrl but in the class, the field name is incorrectly shortened to sUrl.

./node_modules/.bin/pbjs -t json -o test.json test.proto
./node_modules/.bin/pbjs -t static-module -w commonjs -o test.js test.proto
./node_modules/.bin/pbts -o test.d.ts test.js
