✨ Add ability to turn off dates in search

[yahav2305]

Is your feature request related to a problem? Please describe.
I am building a website in which the dates of each page doesn't matter. For that reason, I don't specify dates in the frontmatter of my pages. However, I noticed that in the search bar all of my pages have the date 1 January 0001 since I don't specify my own date.

Describe the solution you'd like
I would like for there to be a switch in the config files. Ideally, when the switch is disabled nothing will change, but when the switch is enabled the dates won't be shown in the search bar.

Describe alternatives you've considered
Currently I am ignoring it, but it makes the website seem not as polished. Theoretically I can overwrite the JS file that defines the search with one of my own, but I'd rather not do that since It can cause configuration drift, and I don't know JS (which is part of the reason I love Blowfish and Hugo).
