docs: Move tutorial content from GitHub repo into the website

[harshitghagre]

What this PR does:
Moves the tutorial from the GitHub repo into the docs site.

• Updated the Tutorial navbar link to /docs-v1.0.x/tutorial/
• Added all tutorial pages to the docs
• Added tutorial images to the docs site

Tested locally with hugo server and everything works fine.

Why we need it:
Right now the Tutorial link opens GitHub. This keeps the tutorial inside the docs site and makes it easier to follow.

Which issue(s) this PR fixes:
Fixes #6745

Does this PR introduce a user-facing change?:

• Users can now read the full tutorial directly on the docs site
• Breaking change: No

Thanks @harshitghagre, this seems like a good idea.
However, there is one issue:

The tutorial content is for v0, not v1

• install-piped.md downloads piped_v0.50.1 binary (hardcoded)
• piped.yaml in pipe-cd/tutorial uses platformProviders, this is the v0 config schema. v1 uses a plugin-based architecture with a completely different config format and binary (pipedv1)
• The pipe-cd/tutorial repo itself hasn't been updated since Feb 2025 (last commit bumped images to v0.50.1).

We don't have a v1 tutorial repo yet.

So, placing this under v1 is wrong, users will install a v0 binary with v0 config, and either get failures or unexpected behavior.

You can retarget this to docs-v0 instead : )
Feel free to ask any doubts you might have regarding this

@harshitghagre One more thing, before making such big changes lets discuss things with all the members and contributors , you can tag me, @rahulshendre, @eeshaanSA or @khanhtc1202 to discuss things before going for a PR, without discussing it leads to something like this above (v0, v1 issue), so discuss things early tag people, tag again if they don't reply, people like rahul and eeshan are always open to guide through this, keep going!!! ❤️

thanks for review @rahulshendre , the website was showing v1 by default so I just went with that, didn't realize the tutorial content was still on v0 now i've updated please review.
