Upcoming events and layout fixes

[kattni]

• The upcoming events were not displaying on the homepage due to a flipped operator.
• The string "Nothing at the moment..." is no longer hardcoded into macros.py which means it will now be translated.
• Blog post titles now render at the same height as site-section titles.
• Overall layout is now more visually centered.

PR Checklist:

• All new features have been tested
• All new features have been documented
• I have read the CONTRIBUTING.md file
• I will abide by the code of conduct

Looks good - one minor suggestion, and one request for a related tweak: you've added padding at the top of the blog post title to account for the (absent) breadcrumbs; it looks like there's a similar need on the News/Events/Resources landing page.

As written, this will invoke the macro twice. That's not a huge problem, but it's one we can avoid with {% set %}

Suggested change

	{% if upcoming_events(files) == None %}
	Nothing at the moment...
	{% else %}
	{{ upcoming_events(files) }}
	{% set events = upcoming_events(files) %}
	{% if events %}
	{{ events }}
	{% else %}
	Nothing at the moment...

I didn't commit this directly because I think there still needs to be whitespace around the string for translation to not pull the Jinja into the translation string.

👍 Looks awesome - thanks for those fixes!
