fix syntax error with tekton results data model diagram

[cmorinupgrade]

Changes

Mermaid does not support titles for graph. If we want to have a title we would need to proceed with:

graph BT
  title[Tekton Results Data Model]
  B(TaskRun) --> |Record| A[Result]
  C(Log) --> |Record| A
  D(PipelineRun) --> |Record| A

which would produce:

However, there is a header just above the diagram so the title is redundant.

I propose that we remove the title completely.

Hi @cmorinupgrade. Thanks for your PR.

I'm waiting for a tektoncd member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Hey @cmorinupgrade, is this related to an issue on the docs site? If so it might just be a matter of updating the mermaid version used on the website as the current syntax is working on GitHub: https://github.com/tektoncd/results?tab=readme-ov-file#data-model

Title support was added in mermaid 9.3.0

Good catch. Granted we could update the version! Repeating the title would still be duplication though. I would personally do both update the version and remove the repeated title. I removed it to match the same pattern we can see under Life of a Result section (we do not add the title again in the diagram).

I will leave it up to the reviewers to decide.

Thanks Alan

Sounds good. I've also opened a PR to see if the updated version works on the website 🤞 https://github.com/tektoncd/website/pull/588

Edit: that seems to have done the trick

Ah I was unable to respond in time: This issue is known and I had opened issue about it, closed due to inactivity: https://github.com/tektoncd/website/issues/544. As per last discussion, we are using a certain hugo theme in our tektoncd website. Last time I checked the theme hasn't updated the mermaid version. It seems to be updated now.
