[TYPESCRIPT_ANGULAR] Bug - swagger-codegen-cli-v3 generates not well formatted README.md

Description

I'd like to generate typescript-angular client with https://hub.docker.com/r/swaggerapi/swagger-codegen-cli-v3.
Everything works fine but the generated README.md misses the code fencing closing (```) after
npm install PATH_TO_GENERATED_PACKAGE/dist.tgz --save in the consuming section/without publishing part so the README.md is not well formatted.

Swagger-codegen version

swaggerapi/swagger-codegen-cli-v3:latest (3.0.18)

Swagger declaration file content or url

http://petstore.swagger.io/v2/swagger.json

Command line used for generation

docker run --rm -v ${PWD}:/local swaggerapi/swagger-codegen-cli-v3:latest generate \
-i http://petstore.swagger.io/v2/swagger.json \
-l typescript-angular \
-o /local \
-DnpmName=somepackagename

Suggest a fix/enhancement

Please add the missing code fencing closing (```) after npm install PATH_TO_GENERATED_PACKAGE/dist.tgz --save

Thanks in advance,
Lajos

Reproduce the issue with the listed Docker command and inspect the generated README.md, especially the consuming section/without publishing part. Find the TypeScript Angular template that produces this section and verify the closing code fence is present in the generated output; completion is a correctly fenced README.md.
