Rename fsapi.FlowsheetExport dict() method and model_objects field to resolve Pydantic 2.0 warnings

[lbianchi-lbl]

Fixes/Resolves: #1344

(replace this with the issue # fixed or resolved, if no issue exists then a brief statement of what this PR does)

Summary/Motivation:

Changes proposed in this PR:

• Replace calls to .dict() with .model_dump()
  • This is a straightforward change since it's just tracking changes in the Pydantic API
• Rename model_objects field to exports due to the model_* namespace being reserved by Pydantic
  • This could also be resolved by "unreserving" the model_* namespace
  • However, I think we should not do that if possible, otherwise it could be confusing for fields/methods where model_ refers to completely different things coexisting in the same class
  • This is a more meaningful change, and the choice of alternative name should be discussed
  • I chose exports on the basis that the item class is named ModelExport
  • Everyone should feel free to come up with feedback and/or alternatives, but I think the choice should ultimately be up to @dangunter and @MichaelPesce
• Before merging this PR, we should thoroughly check whether the same changes should be applied to watertap-org/watertap-ui as well

@lbianchi-lbl the changes look fine to me. We'll have to update the UI accordingly - essentially just replace all references of fs_exp.model_objects with fs_export.exports. I've created a PR for that here

[dangunter]

I like the name "exports"

This is good, thank you Ludovico for your help dealing with Pydantic.

I think @MichaelPesce might have gotten the short end of the stick based on the sizes of the changes in watertap-org/watertap-ui#114 😅
