Fix: flowchart-elk e2e test #6102

[kairi003]

📑 Summary

Fix e2e test for flowchart-elk.

Resolves #6102

📏 Design Decisions

• change maxWidthValue range for "7-elk" and "8-elk".
• change svg.querySelectorAll to svg[0].querySelectorAll because of type errror.
• change ` to " in mermaid text for "Wrapping long text with a new line", because back quote is invalid syntax.
• rename duplicate test name: "Sub graphs and markdown strings".

Changing the expectation instead of the implementation could break compatibility, but in this case, I believe it’s fine.

This is because the changed part was enabled when CI was stopped, so it hadn’t been tested before.

To explain further, describe('Flowchart ELK') was describe.skip('Flowchart ELK') until 0dff4ca. When this commit was merged, the e2e tests weren’t running due to API rate limits.
