Dev tooling - update command - tooling help and Quarkus guides do not reflect that the changes get applied by default

[rsvoboda]

Describe the bug

Tooling help and Quarkus guides are talking about logging of Quarkus-related recommended updates, but in reality the changes get applied to the application.

https://github.com/quarkusio/quarkus/pull/32013 PR didn't touch docs and description of the commands/tasks.

The issue affects:

• Quarkus CLI
• Maven plugin
• Gradle plugin

Commands/tasks description are different for each tool, the description should be unified unified.

Help and guides are talking about logging of Quarkus-related recommended updates.

• Gradle guide is not talking about update task at all.
• CLI and Maven plugin guides will need to be updated to reflect current behaviour (available commands, command output example, etc.)

Commands/tasks descriptions:

• https://github.com/quarkusio/quarkus/blob/main/devtools/cli/src/main/java/io/quarkus/cli/Update.java#L12
• https://github.com/quarkusio/quarkus/blob/main/devtools/maven/src/main/java/io/quarkus/maven/UpdateMojo.java#L25
• https://github.com/quarkusio/quarkus/blob/main/devtools/gradle/gradle-application-plugin/src/main/java/io/quarkus/gradle/tasks/QuarkusUpdate.java#L113

Documentation:

• https://github.com/quarkusio/quarkus/blob/main/docs/src/main/asciidoc/cli-tooling.adoc?plain=1#L252
• https://github.com/quarkusio/quarkus/blob/main/docs/src/main/asciidoc/maven-tooling.adoc?plain=1#L1059
• https://github.com/quarkusio/quarkus/blob/main/docs/src/main/asciidoc/gradle-tooling.adoc?plain=1

Expected behavior

Tooling help and Quarkus guides reflect the recent changes to the update command where the changes get directly applied.

SIDE NOTE: This change of behaviour could be also mentioned in https://github.com/quarkusio/quarkus/wiki/Migration-Guide-3.0

Actual behavior

Tooling help and Quarkus guides are talking about logging of Quarkus-related recommended updates, but in reality the changes get applied to the application.

https://github.com/quarkusio/quarkus/pull/32013 PR didn't touch docs and description of the commands/tasks.
