Add ANZT6W tournament page

[JWWolstenholme]

This PR adds an article for the ANZT6W tournament.

There have been a bunch of ANZT tournaments since this one that are undocumented in this wiki. I'm planning on documenting them all in one big pull request in the future. Let me know if that's not a good idea. They are:

This PR also adds entries on the tourney index page and ANZT tourney index page for all following tournaments after 6W. They are:

• ANZT7S
• ANZT7W
• ANZT8S
• ANZT8W
• ANZT9S
• ANZT9W
• ANZT10S
• ANZT10W
• ANZT11S
• ANZT11W
• ANZT12S

Someone else has edited same files as you did. Please check their changes in case they conflict with yours:

• Add Resurrection Cup 2024 tournament and listing. #12582, files:
  • wiki/Tournaments/en.md

When adding a tournament to the tournament listings in other languages, make sure to adjust the date formats. They're currently all using the English format.

I suggest adding all ANZT tournaments to the index page and tournament listings in this PR already. Once the full articles are PR'd, you then only need to add in the links. This will also avoid any merge conflicts that arise when doing multiple PR's for the same index page.

I will also suggest doing a new PR for each tournament, or PR's for each year (so bundle the summer and winter tournaments). Large PR's with tons of tournaments all at once are a daunting task to review. By separating them into smaller chunks, they can be reviewed and taken care of 1 by 1. Divide and Conquer type of deal.

@Albionthegreat Thanks for the feedback. I've:

• Corrected the dates on the translated pages using the changes you suggest
• Added entries, but not dead links, to all the other ANZT tourneys since 6W.
  • I made sure to follow each translation's date format.
• Rebased this PR onto master since I've left this PR sitting for so long

I'll follow your advice and use smaller PRs for each tournament or two. Apologies for all the force pushes, hopefully that's not an issue.

I've also included entries for tourneys 1 through 4 which were already included in the main tourney index page, but missing from the ANZT tourney index page. Forum links:

• ANZT1
• ANZT2
• ANZT3
• ANZT4

Just to clarify, this PR is ready for anyone to review it. I'm done making changes for now.

I'll take a look at the tournament page itself later. The listings and index pages look good!

Thanks for the feedback @Albionthegreat. I've incorporated all your suggestions.

Looks like I'm outdated on new styling since I was last here 6-7 years ago.
