Add configuration parameter to indicate spring boot track

[gabheadz]

Is your feature request related to a problem? Please describe.
Define a configuration flag to indicate to the ca task which track of spring-boot to use.

Describe the solution you'd like
If and only if we decide to provide this level of configuration, then I would imagine a parameter like this:

gradlew ca --package=com.example.demo --type=reactive --name=demo --coverage=jacoco --lombok=true --bootVersion=VERSION_2

or

gradlew ca --package=com.example.demo --type=reactive --name=demo --coverage=jacoco --lombok=true  --bootVersion=VERSION_3

if bootVersion=VERSION_3 is selected, then javaVersion should be automatically defined as JAVA_17

Describe alternatives you've considered

One alternative is to keep the scaffolder versions up to 2.x.x using spring-boot 2.7.x and produce a new major version of the scaffolder 3.x fixed for spring boot 3.x.

Hi @gabheadz, I think that we should only support the latest release of Spring Boot, what do you think @dbuos @santitigaga @maocq?

[santitigaga]

I think the same.
If consumer use the plugin version 3.x we could generate the project with spring boot 3. or if you use the plugin version 2.x we could generate the project with spring boot 2.

We might need to change something in the previous version (2.x). we can do this with a branch to update this version.

It will not be implemented
