cdk go template files break go commands

### Describe the bug

It's hard to use the CDK as a deployment tool in go projects because the node_modules/ directory contains go files with invalid names:
node_modules/aws-cdk/lib/init-templates/app/go: invalid input file name "%name%.template.go"
node_modules/aws-cdk/lib/init-templates/sample-app/go: invalid input file name "%name%.template.go"

These look like template files, so in don't think the names are important. If they had some extension other than '.go', they wouldn't interfere with go fmt, lint, test, etc.

### Expected Behavior

go test -v ./... -tags unit
? github.com/gg-cloud/lambda-bootstrap-rds [no test files]
=== RUN TestGetLogger
=== RUN TestGetLogger/sdf
{"level":"info","version":"my_version","message":"my_message"}
--- PASS: TestGetLogger (0.00s)
--- PASS: TestGetLogger/sdf (0.00s)
PASS
ok github.com/gg-cloud/lambda-bootstrap-rds/log (cached)
=== RUN TestGetDbConnection
=== RUN TestGetDbConnection/local-docker:valid_postgres_db
--- PASS: TestGetDbConnection (0.00s)
--- PASS: TestGetDbConnection/local-docker:valid_postgres_db (0.00s)
PASS
ok github.com/gg-cloud/lambda-bootstrap-rds/sql (cached)

### Current Behavior

make unittest
package github.com/gg-cloud/lambda-bootstrap-rds/node_modules/aws-cdk/lib/init-templates/app/go: invalid input file name "%name%.template.go"
package github.com/gg-cloud/lambda-bootstrap-rds/node_modules/aws-cdk/lib/init-templates/sample-app/go: invalid input file name "%name%.template.go"
go test -v -tags unit
? github.com/gg-cloud/lambda-bootstrap-rds [no test files]

### Reproduction Steps

gofmt -w -s .

### Possible Solution

rename those files from *.go to *.gotemplate

Inspect node_modules/aws-cdk/lib/init-templates/app/go and node_modules/aws-cdk/lib/init-templates/sample-app/go, focusing on the files named %name%.template.go. Run gofmt -w . or make unittest to reproduce the invalid input filename, then verify that go test -v ./... -tags unit completes without errors after the template filenames no longer match Go source files.
