Linking to a page with a title of the format "YYYY/MM/DD - <text>" will cause the 'Page Information' page to break

Issue Summary

This is reproducible on Data Center: Yes

When a page has a title using a format that includes a date and some text after it, other pages that link to it will not be able to have the "Page information" part viewed due to a "500" error due to the "outgoing links" part not rendering it.

Steps to Reproduce

1. Create a page that starts with 'YYYY/MM/DD - <text>'. For example:
   1. "2022/11/18 - Test from Atlassian"

1. Create a second page, and add a link to the first created page.
2. Under the page with the link (second page), tap the ellipsis button at the top-right > Advanced information > Page information

Expected Results

The page information should be displayed.

Actual Results

The following error message is triggered in the UI:

We'll be back in a flash

We've encountered a small problem, but we should have it sorted out soon.

Notes

• From the internal logs, the following stack trace is observed (using the example from above):

message: Unable to render Velocity Template, '/pages/viewinfo.vm'
...
 stack: org.apache.velocity.exception.MethodInvocationException: Invocation of method 'getOutgoingLinks' in class com.atlassian.confluence.pages.actions.PageInfoAction threw exception java.lang.NumberFormatException: For input string: "2022/11/18 - Test from Atlassian" at /pages/viewinfo.vm[line 355, column 39]
...
Caused by: java.lang.NumberFormatException: For input string: "2022/11/18 - Test from Atlassian"

• If the page with the title in question has an attachment on the body (I.E. a PPTX), the error will happen on the page itself.

Workaround

On the page title, add the text before the date format.
