feat: upgrade to Wagtail 7.x support

[hoheinzollern]

Hey, I have a Puput/Wagtail installation that I needed to update, and took the chance to update Puput's dependencies to the latest versions and check that it works. The interesting bit is that the wagtail_hooks are no longer needed since Wagtail 5.

• Update Wagtail dependency to support versions 5.2 through 7.x
• Update django-el-pagination, django-taggit, and wagtail-markdown dependencies
• Remove deprecated wagtail_hooks.py (Draftail customizations)
• Add Python 3.12 and Wagtail 7 framework classifiers
• Bump version to 2.3.0

Rationale for wagtail_hooks.py removal:
The Draftail rich text editor was replaced in Wagtail 5.0+. The blockquote and code features previously added via hooks are now built-in to Wagtail and can be enabled via WAGTAILADMIN_RICH_TEXT_EDITORS configuration.

See Wagtail documentation:

• https://docs.wagtail.org/en/stable/extending/rich_text_internals.html
• https://docs.wagtail.org/en/stable/extending/extending_draftail.html

Users can enable these features in settings.py:

WAGTAILADMIN_RICH_TEXT_EDITORS = {
    'default': {
        'OPTIONS': {
            'features': ['blockquote', 'code', ...]
        }
    }
}

This change maintains all functionality while aligning with modern Wagtail best practices and removing deprecated code.

Nice one! I've tested that vs Wagtail 7.3 and it's working fine.

Only note vs your settings above is I think "WIDGET" is a required param now, this works for me:

WAGTAILADMIN_RICH_TEXT_EDITORS = {
    "default": {
        "WIDGET": "wagtail.admin.rich_text.DraftailRichTextArea",
        "OPTIONS": {
            "features": [
                "h2",
                "h3",
                "h4",
                "bold",
                "italic",
                "ol",
                "ul",
                "hr",
                "link",
                "document-link",
                "image",
                "embed",
                "blockquote",
                "code",
            ]
        },
    }
}

It'd be great to get this merged since Wagtail 6.3 LTS will be out of support soon (https://github.com/wagtail/wagtail/wiki/Release-schedule ).

• Still forces wagtail<7 in the requirements. #303

Great to hear! I've also taken care of updating the dependent wagtail-markdown package, as I was getting a warning about the outdated dependencies:

• Replace bleach with nh3 for HTML sanitization torchbox/wagtail-markdown#163

Ideally, if doing a release, it would be helpful to have that merged first and update the dependencies.

@therefromhere I tried to clean up the changelog with a force push, somehow it got closed. Feel free to reopen.
