Update the packages/etc. for Julia 1.9

[jlperla]

• [ ] Make sure it builds locally on juptyerbook with the current main branch and 1.8.
• [ ] Bump your juliaup to 1.9
• [ ] Delete the notebooks/Manifest.toml file then do ]activate notebooks and ] instantiate in the repo.
  • That will download all of the packages/etc. If there are major errors or incompatibilityies we should discuss them.
• [ ] I think you have to change https://github.com/QuantEcon/lecture-julia.myst/blob/main/lectures/_config.yml#L70-L80 and other things that point to 1.8 directly.
• [ ] Run the full lecture notes suite - look for errors.

After that we will need to update the continuous integration stuff.

• [ ] Change https://github.com/QuantEcon/lecture-julia.myst/blob/main/.github/workflows/cache.yml#L37 and https://github.com/QuantEcon/lecture-julia.myst/blob/main/.github/workflows/ci.yml#L34 and https://github.com/QuantEcon/lecture-julia.myst/blob/main/.github/workflows/publish.yml#L38
• [ ] Then in the PR we can see how it does and talk to @mmcky

I have run the full lecture suit with julia 1.9. There were not any major issues. A few notes are that in "14. Geometric Series for Elementary Economics" there was an issue with the latex compile with the symbolics package (I think this is due to my local set up though). In "20. Krylov Methods and Matrix Conditioning" the "OrdinaryDiffEq.FunctionMap" package gave a warning about a conflict (still seemed to run fine though). In "60. Multiplicative Functionals" there is a panel with a whole bunch of graphs and the text overlaps (this could be a theme or build issue).

[jlperla]

Great! Yeah you will probably need a local latex isntallation working on your machine to see the titles correctly for the plots. Not sure if that is a theme issue or not.

Why don't you copuy/past the wranings/etc. as a list here to discuss? Some might be deprecations which we want to trigger new issues for.

I should have put this first but the code that caused these warnings was,

@Jonah-Heyl Are you ready to close this issue? If so, I would do so.

[Jonah-Heyl]

Yes, the plots are in a different issue now
