Namespace summary pages treat vertical bar in ket notation as new table column

[tcNickolas]

Describe the bug

Namespace summary pages treat vertical bar in ket notation as a new table column, making for weird formatting.
The ket notation is done using Unicode (see example in Reset).

To Reproduce

See https://docs.microsoft.com/en-us/qsharp/api/qsharp/microsoft.quantum.intrinsic, Reset and ResetAll summaries as an example.

Expected behavior

This should be shown as normal text. Maybe we can use something along the lines of https://stackoverflow.com/questions/49809122/vertical-bar-symbol-within-a-markdown-table when generating the docs.
