Add accordion for evidences section

[therealtoastycat]

Hi @chrismaddalena,

Description of the Change

When many evidences are added to a finding, the finding summary looked a bit messy so I've modified the 'report_detail' template to include an accordion feature, allowing for the collapse and expansion of evidence sections.
In addition, I've made the 'Attach Evidence' button appear even if evidence has already been added to the finding.:

Alternate Designs

None

Possible Drawbacks

None observed

Verification Process

Tested on the last release with google chrome.

Release Notes

• Collapse findings' evidences in accordeon

Cheers,
ToastyCat

@therealtoastycat I pushed a small change that seems to have broken GitHub. The commit bring sup a 500 error and the PR can't be merged. I'll merge this once this gets sorted out on GitHub's side.
