Docs: Autogenerated code in examples doesn't work for 999-SNAPSHOT

[fedinskiy]

Describe the bug

Multiple Quarkus guides[1][2][3] contain code examples for creation of application using maven-plugin. If we use them with version 999-SNAPSHOT, these code examples start with io.quarkus.platform:quarkus-maven-plugin:999-SNAPSHOT:create. The problems is, quarkus-maven-plugin uses io.quarkus.platform group only for released versions, and uses io.quarkus for 99-SNAPSHOT. Because of that, the code in examples fails with exception Could not find artifact io.quarkus.platform:quarkus-maven-plugin:jar:999-SNAPSHOT .

[3] https://quarkus.io/version/main/guides/getting-started-dev-services#bootstrapping-the-project

Expected behavior

Code from tutorials should not fail an, probably, should use io.quarkus:quarkus-maven-plugin:999-SNAPSHOT:create command

Actual behavior

The code fails

How to Reproduce?

1. Open any of guides linked above, eg https://quarkus.io/version/main/guides/security-oidc-code-flow-authentication-tutorial#create-the-maven-project
2. Copy generator code for maven:

mvn io.quarkus.platform:quarkus-maven-plugin:999-SNAPSHOT:create \
    -DprojectGroupId=org.acme \
    -DprojectArtifactId=security-openid-connect-web-authentication-quickstart \
    -Dextensions='resteasy-reactive,oidc' \
    -DnoCode

3. Run the code, the generation fails
4. Edit the platform part out:

mvn io.quarkus:quarkus-maven-plugin:999-SNAPSHOT:create \
-DprojectGroupId=org.acme \
-DprojectArtifactId=security-openid-connect-web-authentication-quickstart \
-Dextensions='resteasy-reactive,oidc' \
-DnoCode

5. Run the code, the generation succeeds

I will adjust it but keep in mind that the main documentation is for people who knows what they are doing.

In this case, you would either have to also install locally a working platform or use the io.quarkus groupId.

I will adjust to use the io.quarkus groupId: quarkusio/quarkusio.github.io#1853
