Change more classes to records

[Defeatomizer]

This PR changes more classes to the new record feature of J16.
This PR changes the following classes:

• net.mcreator.blockly.BlocklyCompileNote
• net.mcreator.blockly.data.NamedInput
• net.mcreator.element.types.Recipe.OptimisedRecipe
• net.mcreator.minecraft.api.ModAPI.Implementation
• net.mcreator.ui.MCreatorDropTarget
• net.mcreator.ui.action.impl.workspace.resources.StructureImportActions.Structure
• net.mcreator.ui.vcs.WorkspaceMergeHandles
• net.mcreator.vcs.SyncTwoRefsWithMerge.SyncResult
• net.mcreator.vcs.diff.AffectedObjectWithType

The following classes pretended to become records too:

• net.mcreator.generator.GeneratorWrapper - Turning it into a record would cause it's generator parameter to become visible by plugins, the only way to prevent that is to use the following code:
  
• net.mcreator.ui.validation.validators.CommaSeparatedNumbersValidator - I changed type of its holder parameter from VTextField to JTextField, like it's done in all the other validators;
• net.mcreator.ui.vcs.MCreatorWorkspaceSyncHandler - I added @SuppressWarnings annotation to it (it's not a data class so should remain untouched);
• net.mcreator.workspace.WorkspaceFileManager.SaveTask - check the previous entry.

Sometimes following code cleanup suggestions makes things less clear / introduces bugs. Each cleanup should be weighted if it is worth it
