Blender: Publisher collect workfile representation

[kaamaurice]

Brief description

Like collect_workfile behavior from Maya host, Blender should ba able to publish workfiles.

Description

• I have updated collect_current_file.py with the code from maya plugin collect_workfile to be able to publish workfile representation.
• Action are available to save file if needed.

This is more of a general note for all hosts - not specific to only this PR. Having the functionality is great - so nice work!

I have a feeling that 90% of the code here is the same across all hosts due to the existence of the work API.
Wouldn't it make more sense to have a single global Workfile collector that works across all hosts. And per host only implement InstancePlugin collectors that operate on families = ["workfile"] to collect additional data for the instance specific to that host.

So that e.g. in Blender that would be:

class BlenderWorkfileDataCollector(pyblish.api.InstancePlugin):
    def process(self, instance):
        instance.data["frameStart"] = bpy.context.scene.frame_start
        instance.data["frameEnd"] = bpy.context.scene.frame_end

Slightly simplified example due to missing imports and instance plugin attributes like order and families

Or is it ok to maintain this duplicated code across all hosts? :)

It works fine, no problems using Blender 3.2.1
