Updated several things under the tutorial page for the 2025 beta release
Added an extra item for the 2025 beta release under "Tutorials" and started to clean up the subsequent pages:
- Changed all the links under the previous release to point to the tagged 10fb-legacy branch
- Updated the links under 2025 beta release to point to master branch
- Removed link to all notebooks not being available for 2025 beta release
- Added cheat sheet to convert from previous to new release [needs to be filled]
- Cleaned up the c++ frameworks and made a new page with the updated analysis examples for 2025 release [https://opendata.atlas.cern/docs/documentation/example_analyses/example_analyses_intro] - the latter needs updating
I'm sure I have missed a lot and that there are still things which are missing, pointing to the wrong place, misleading etc. Any fresh eyes which could have a look and a click-around is very much appreciated :-)
