Add package name in doc.go to pass Go linter checks

Currently golint ./... is giving the following error:

package comment should be of the form "Package swagger ..."

Another option is to add // +build !codeanalysis during generating the file

Using this approach prevents parsing of the files, and significantly reduced our memory consumption during build time.

The linter-related packages and their versions I use currently

golang.org/x/lint v0.0.0-20210508222113-6edffad5e616
golang.org/x/tools v0.0.0-20200130002326-2f3ba24bd6e7
