pkp/immersion#103 Elements must meet minimum color contrast ratio

[israelcefrin]

Fix the low contrast ratio in the date component.

Hi @israelcefrin, what if instead of using darkslategrey which isn't used in the theme, we instead applied the text-muted class to the date in templates/frontend/objects/issue_summary.tpl? Then we can remove this CSS class and use the existing bootstrap class which has a 4.69:1 contrast ratio and is already used elsewhere in the theme (e.g. for announcement dates).

Hi @kaitlinnewson, good call! I've already adjusted and submitted a new commit to use BootStrap class name. I haven't noticed we could use all BS framework.

Thanks @israelcefrin! Merged and cherry-picked to main.
