Use local storage to remember user choices

[mhalbritter]

If a user changed e.g. Gradle to Maven last time, there is a high chance that they want it the next time, too. So we should remember the choices for:

• Java (version)
• Project
• Language
• Maybe Spring Boot version?

We could take a look what a IDE remembers.

Hi Moritz,

I hope you're doing well!

After reviewing the requirements , I took the initiative to implement this feature.

Here's a summary of what I've done:

Implemented local storage caching for form state in start.spring.io.
Thoroughly tested the functionality across different scenarios to ensure reliability.
Caching implemented to these fields:
Project, Language, Spring boot, Packaging and Java version.

I believe that this feature aligns well with the goals of the project and could greatly enhance the user experience. Before proceeding further, I wanted to confirm if you're open to accepting this contribution.

If you agree, I can proceed with opening a pull request. Alternatively, if you have any specific requirements or suggestions, please let me know, and I'll be happy to accommodate them.

Looking forward to your guidance on this matter.
