[Feature request] Add a `codeAction` to generate the serialVersionUID field

Problem Statement

As the Eclipse IDE: Which class implements the Serializable, we need to put a field: private static final long serialVersionUID = X;. Where X is a number type long be generated by the tool serialver of Java.

Ideas or possible solutions

Reference: Java – How to generate serialVersionUID

Conclusion

Thank you for the hard-working to make this LS for Java, I really appreciate it.

@snjeza today, I make it works with a little tweak like the picture below (includes your patch or without it):

So this issue is resolved. I want to give to you huge respect.

A ridiculous that, when I test in Lua demo the format:

local settings = {
  java = {
    settings = {
      url = "/path"
    }
  }
}

print(settings.java.settings.url)
-- Output: /path

But with that format in nvim-jdtls it doesn’t work. I need to explicit it for the key of table settings:

local settings = {
  ["java.settings.url"] = "/path"
}

One improvement is to show this quick fix suggestion at the light bulb regardless of whether the “missingSerialVersion” flag is enabled or not.
