Recipe to autofix UpperEllCheck.

[Anmol202005]

Implement an OpenRewrite recipe to automatically fix Checkstyle UpperEll violations by converting lowercase 'l' suffix in long literals to uppercase 'L'.

UpperEll Check: https://checkstyle.sourceforge.io/checks/misc/upperell.html#UpperEll .

Example

// Before
long value = 123l;

// After  
long value = 123L;

Tasks:

1. Create UpperEll recipe class
2. Add visitor to transform long literals
3. Write tests using OpenRewrite test framework
4. Add conditional execution (only when UpperEll check is enabled)
5. Package the recipe

As part of this issue, please investigate integration with OpenRewrite ecosystem, such as:

• recipe metadata (methods getTags(), getEstimatedEffortPerOccurrence(), etc.)
• recipe discovery (e.g., src/main/resources/META-INF/rewrite/checkstyle.yml containing recipe declarations)

Also I'm not sure we need xxxRecipe as a suffix. Could you check existing open source recipes, what pattern do they follow for naming?

[Anmol202005]

getTags() - Returns a set of tags for categorizing the recipe
getEstimatedEffortPerOccurrence() - Returns a Duration indicating estimated time savings per occurrence

Example:

@Override
public Set<String> getTags() {
    return Set.of("java", "testing", "junit", "migration");
}

@Override
public Duration getEstimatedEffortPerOccurrence() {
    return Duration.ofMinutes(10); // Custom estimate based on complexity
}

OpenRewrite recipes don't use "Recipe" suffix - Mostly action names like ChangePackage, MethodNameCasing, RemoveUnusedImports are used.

Let's follow same pattern and rename existing recipes as part of this issue. Recipe suffix is redundant. For recipes name lets use check names as they are displayed here https://checkstyle.sourceforge.io/checks.html
