Automatically install tool's specified version if not present

[marcwrobel]

Is your feature request related to a problem? Please describe

Currently when running a tool that is not installed, but has its version specified in the .tool-versions file, the command fails with a message such as:

$ mvn
No preset version installed for command mvn
Please install a version by running one of the following:

asdf install maven 3.9.2
...

Describe the proposed solution

Instead of having an error, the tool could be automatically installed using the provided command. This would be really great for:

• teams working on a project having a dedicated committed .tool-versions, as there would be no need for them to install the new version before re-running the command,
• continuous integration, as it would remove the need to have a dedicated step to make sure the correct tool's version is installed before using it (when the installed tool are cached).
