let devdocs rely ruby 4.0.3,no longer rely ruby 3.x

[yzytom]

If you’re adding a new scraper, please ensure that you have:

• Tested the scraper on a local copy of DevDocs
• Ensured that the docs are styled similarly to other docs on DevDocs

• Added these files to the public/icons/your_scraper_name/ directory:
  • 16.png: a 16×16 pixel icon for the doc
  • 16@2x.png: a 32×32 pixel icon for the doc
  • SOURCE: A text file containing the URL to the page the image can be found on or the URL of the original image itself

If you're updating existing documentation to its latest version, please ensure that you have:

• Updated the versions and releases in the scraper file
• Ensured the license is up-to-date
• Ensured the icons and the SOURCE file in public/icons/your_scraper_name/ are up-to-date if the documentation has a custom icon
• Ensured self.links contains up-to-date urls if self.links is defined
• Tested the changes locally to ensure:
  • The scraper still works without errors
  • The scraped documentation still looks consistent with the rest of DevDocs
  • The categorization of entries is still good

Pull request overview

This PR attempts to switch the project from Ruby 3.4.8 to Ruby 4.0.5 across the runtime/version pins and regenerates the Gemfile.lock accordingly. It also constrains html-pipeline to ~> 2.14, explicitly adds ostruct and webrick (libraries that have been extracted from the Ruby stdlib), and adds require 'ostruct' to the images filter test.

Changes:

• Bump Ruby version pin to 4.0.5 in .ruby-version, Gemfile, Gemfile.lock, Dockerfile, and Dockerfile-alpine.
• Add ostruct and webrick gem dependencies and constrain html-pipeline to ~> 2.14; regenerate Gemfile.lock (major upgrades of activesupport, sinatra, rack, etc., and platform-specific entries/CHECKSUMS).
• Add require 'ostruct' to test/lib/docs/filters/core/images_test.rb.

File	Description
.ruby-version	Pins Ruby to 4.0.5.
Gemfile	Updates Ruby pin to 4.0.5; adds ostruct and webrick; constrains html-pipeline to ~> 2.14.
Gemfile.lock	Regenerated lockfile reflecting new Ruby version, multi-platform entries, CHECKSUMS, and upgraded gems.
Dockerfile	Updates base image to ruby:4.0.5.
Dockerfile-alpine	Updates base image to ruby:4.0.5-alpine.
test/lib/docs/filters/core/images_test.rb	Adds explicit require 'ostruct' to support newer Ruby where it's no longer autoloaded.

Note: Ruby 4.0.5 does not exist as a released version, and no ruby:4.0.5 Docker images are published. The PR title/intent ("rely ruby 4.0.3") is also inconsistent with the actual 4.0.5 pin in the diff. Additionally, .tool-versions (ruby 3.4.8) and README.md (Ruby 3.4.1) still reference older 3.4.x versions and were not updated.
