[rohanbabbar04]

Closes #520

Description

• Moved distributions to distributions/gallery and distributions/img.
• Set Up Examples Gallery with a basic/test example of Maximum Entropy.

Checklist

• Code style is correct (follows ruff and black guidelines)
• New features are properly documented (with an example if appropriate)

@aloctavodia, I think we should move the examples in the Direct Elicitation and Predictive Elicitation files into the Examples Gallery, as they are functions in PreliZ. So we can completely remove the Examples tab.
For tutorials, we can set them up in the same way as we have done with the Examples.

What do you suggest?

[aloctavodia]

I agree to remove the "example" tab in favour of the "example gallery". I suggest the following organization:

Currently, we have the following examples:

Working with distributions
Direct elicitation in 1D
Direct elicitation in ND
Predictive Elicitation
Global settings

We can divide them into 3 categories, each category will have one or more "cards" for separate examples

Direct elicitation --> Direct elicitation in 1D, Direct elicitation in ND
Predictive elicitation --> Predictive Elicitation. For the moment is ok to have a single card, but better to split it into two, and I have a third card/example I could add.
Not-sure-the-name --> Working with distributions, Global settings

In the future, we could add other categories like "Tutorial".

What do you think about adding an "external examples" Category. There we could list the following resources

• Prior elicitation introduction https://arviz-devs.github.io/Exploratory-Analysis-of-Bayesian-Models/Chapters/Prior_elicitation.html
• Prior sensitivity checks https://arviz-devs.github.io/Exploratory-Analysis-of-Bayesian-Models/Chapters/Model_criticism.html#prior-sensitivity-checks
• PriorDB https://n-kall.github.io/priorDB/

Changes implemented post our comments:

1. Have removed the Examples sections, in favor of Examples Gallery.
2. Shifting the already present Examples into the gallery , currently having three categories.(like we discussed in the last comment).
3. Would need some advice/suggestions on the image displayed on the cards 😅.
4. Have shifted all the distributions to the distributions folder, and all examples inside the examples folder.

Regarding the external examples, I will open a new PR once the initial gallery is setup...

[aloctavodia]

This is great. I can replace the card images in a separated PR if you want. If we are going to display distributions, probably thicker lines would work better.

Great!!
If all looks good, this is ready to be merged.
