docs: update tarball extension from .tgz to tar.gz in markdown files

[Dindihub]

Proposed changes

Problem: I updated the Tarball extension from .tgz to tar.gz in markdown files in the content folder

Solution: Searched for .tgz mentions in markdown and replaced with tar.gz as indicated in the issue by @mjang

Testing: I ran the Hugo server locally using make watch to ensure my project works properly

Please focus on (optional): .tgz change to .tar.gz in /content markdown files

Note: I ran make link-markdown and make link-check, but neither passed. I left it as is because they highlighted format issues beyond what my PR addresses. For example, there are issues with blockquote, dead links, e.t.c. But with your permission, I can work on them in another PR

I wouldn't worry about this too much: they haven't been a mandatory part of PR work for a while and are due a revisit.

The tarball changes LGTM but adding a full copy of the Hugo binaries is out of scope for the PR or the original issue.

Please remove the changes to the makefile and the bin folder from this PR.

You are right. Let me rebase. Thanks

Done @ADubhlaoich @JTorreG Please review. Thanks

@Dindihub . Thank you so much for your contribution. While I thought I had a commitment to standardize our tarball file extensions with .tar.gz, it's not happening in practice.

I thank you for your work on this PR. We may be able to revive it later. But for now, I'm going to close this without merging.
