Release notes + homepage redesign

[mnocon]

Target: master, 4.6

How to review:

Frontend:

• All the SVG, CSS, SCSS, JS, .eslintignore changes are done by @GrabowskiM and should not be reviewed

My changes:

• Added list of LTS updates in https://ez-systems-developer-documentation--2652.com.readthedocs.build/en/2652/ibexa_products/editions/
  • I believe it's a good place to mention them as it's one of the first pages which people see, LTS Updates are additional features and they can belong to different editions
• Added empty sections to the update page to make things consistent (https://ez-systems-developer-documentation--2652.com.readthedocs.build/en/2652/update_and_migration/from_4.6/update_from_4.6/)
• The homepage has been redesigned to include information about latest LTS update (and LTS updates in general)
• Added missing information for the old releases (4.6.1 - 4.6.18)
• Added Python macros so that adding new releases is more enjoyable and does not require adding any HTML tags

Adding a new release

You can add a new release as in the following example:

[[% set version = 'v4.6.11' %]] # Required if the change log snippet is used
[[= release_note_entry_begin("Ibexa DXP " + version, '2024-09-16', ['Headless', 'Experience', 'Commerce']) =]] # Required: specifes the title of the release, release date and categories. Available categories are: 'Headless', 'Experience', 'Commerce', 'LTS Update', 'New feature'

#### Section header

You can use Markdown here, as usual

[[% include 'snippets/release_46.md' %]] # Optional, generates the full change logs and update guide link. Version variable must be set to use this
[[= release_note_entry_end() =]]
