update spacing in technologies section

[mishaschwartz]

Changes:

• put technology content into a dictionary (more readable)
• move technology content to technology-card.html (where it is used)
• remove unnecessary variables
• remove padding around technologies row (inconsistent with other rows)
• ensure that when the title in a technology card wraps to 2 lines, the content doesn't shift so that it no longer aligns with the other cards
• ensure that technology cards have the same width
