Clarify filter info on exposure level page

[stscijgbot-jwql]

Issue JWQL-199 was created on JIRA by Bryan Hilbert:

In the exposure info section towards the top of an exposure level page, the filter value is reported. However, pupil elements are ignored, which can cause misleading information to appear. In cases where a narrow band (pupil wheel-mounted) filter is used, the information printed lists F150W2, which is the crossing filter.

Pupil wheel based information should also be shown here.

Comment by Bryan Hilbert on JIRA:

Nevermind. I was looking in the wrong place and misinterpreting what I saw. Filter and pupil values are all present in the information, and shown in the proper places.
