Add second tag for spring framework

[thepetk]

What does this PR do?

Adds a second item inside the SpringDetector.GetSupportedFrameworks func. As a result, when the Spring Boot framework is identified inside a project, it adds two tags inside the language.Frameworks

func (s SpringDetector) GetSupportedFrameworks() []string {
	return []string{"Spring", "Spring Boot"}
}

func (s SpringDetector) DoFrameworkDetection(language *model.Language, config string) {
	if hasFwk, _ := hasFramework(config, "org.springframework"); hasFwk {
		language.Frameworks = append(language.Frameworks, s.GetSupportedFrameworks()...)
	}
}

Finally, it will be able to match the given tag of "Spring Boot" whenever it is updated from the registry side. Note, that this solution is backwards compatible. Once the update of the "Spring" tag to "Spring Boot" is done, we can iterate and have only "Spring Boot" as supported network.

Which issue(s) this PR fixes:

fixes #136

Test outputs

I've forced updated locally the tag "Spring" to "Spring Boot" and tested this solution:

// go/pkg/apis/recognizer/devfile_recognizer.go#L151
for _, tag := range devFile.Tags {
  if tag == "Spring" {
	  tag = "Spring Boot"
  }
  if frw := matches(language.Frameworks, tag); frw != "" {
	  frameworkPerDevfileTmp[frw] = nil
	  score += utils.FRAMEWORK_WEIGHT
  }
  if matches(language.Tools, tag) != "" {
	  score += utils.TOOL_WEIGHT
  }
}

And the output is:

[
	{
		"Name": "java-springboot",
		"Language": "Java",
		"ProjectType": "springboot",
		"Tags": [
			"Java",
			"Spring"
		]
	}
]

Can we add a unit test for this change?

@yangcao77 I've updated the mocked values of getDevFileTypes in order to provide Spring Boot as tag

Thanks for the change. Look good to me.
