fix: Add SEO Page Title for 2 pages

[ajitzero]

Description:

• The page title is taken from the h1 tag of a page in this component.
  • For "Operator Decision Tree", the h1 tag was placed within the component for the page and not in the HTML file itself. Moved it into the correct file now.
  • For "Team", there was no h1 tag. Added this now.
• Typo: "Alumn" should be "Alumni". Unrelated to the above, but I noticed it and included it here. I can remove it from here and submit it separately if anyone has strong opinions about that.

Related issue (if exists):
None

Screenshot of fix:

Case	Before	After
Page title of "Operator Decision Tree" & inline # link
Page title of "Team"
Typo in "Team" > "Alumni"

I suggest squash-committing this since I edited the commit messages via GitHub UI and will not pass commit-lint. Fixed commit messages.

Please revert one of the changes (the second example from the PR description) as it is redundant. And also please merge master branch to resolve conflicts. Otherwise, looks good.

I think this heading is not needed. The reason for this is that the heading is still visible in the top header:

Please revert this one.

As a non-native English speaker, I hope this one is right 🙂 I don't really know. Maybe @benlesh can help?

Hi @ajitzero — thank you for the time, care, and thoughtfulness you put into this pull request. I’m sorry we weren’t able to respond in a reasonable timeframe. Since the codebase and surrounding context have moved on and this hasn’t seen recent activity, I’m going to close it for now. That’s a reflection of our delayed triage, not a lack of appreciation for your contribution. If the change is still relevant, please feel welcome to open a fresh pull request against the current codebase. Thank you again for contributing to RxJS and for your patience.
