Improvements to `.tag-cloud`

[alphapapa]

@jarrodmillman pointed out some issues with the "tag cloud" on https://blog.scientific-python.org/posts/.

Here are some issues I've noted as well:

• The readability and clickability of some items is poor
• The size of tags is inconsistent, some being very small (like 3d) and some very long (like traveling-salesman-problem). This is hard to make aesthetically pleasing, as well as being inconsistent for usability and readability.

Some ideas:

• Limit the range of font sizes: smaller tags would be larger, and larger ones would be smaller, resulting in a more even appearance.
• Unify the font sizes completely: every tag would be the same size. The information currently conveyed (the size representing how many posts exist with the tag) could be conveyed by other means, like a number next to the tag.
• Have a separate page for the tag cloud: giving it more space would allow more freedom to display them in useful, creative ways.
• Dispense with the tag cloud entirely: they seem somewhat popular, but whether they're useful to readers is another matter.

@jarrodmillman @stefanv What do you think? Also, who else should we tag for feedback on these ideas? Thanks.

The simplest change for now would be to limit the font size. Perhaps calculate the relative sizes using log or similar, so that the differences aren't that great, but very popular topics still stand out.
