Tests on master fail when project is cloned locally #218

Describe the bug
When the project is cloned from the master branch, one of the test suites fails.

To Reproduce
Steps to reproduce the behavior:

1. Clone this project
2. run npm install
3. run npm run test
4. Two tests for src/readme.spec.js should fail. They should be:
   1. should return readme default template no html content
   2. should return readme default template content

Expected behavior
Tests should not fail when the project is cloned from the master branch.

Desktop (please complete the following information):

• OS: Linux, Manjaro
• Browse Firefox
• Version 86.0

Additional context
The issue seems to be caused by the snapshot README file in src/__snapshots__ folder. The two lines in the file causing the problem are:

1. Copyright © 2019 [Franck Abgrall](https://github.com/kefranabg).<br />
2. Copyright © 2019 [Franck Abgrall](https://github.com/kefranabg).

One of the offending tests is this one:

it('should return readme default template no html content', async () => {
      const result = await buildReadmeContent(
        context,
        defaultNoHtmlTemplatePath
      )

      expect(result).toMatchSnapshot()
    })

It seems like the readme built for test contains a copyright year of 2021 instead of 2019.
