Update Cipher_Suites table to v5.x

[janbrasna]

Fixes #247, #292, april/tls-table#4

Since the simplification after v4.0 and the archival of older more expansive docs aligned with v5.0 guidelines, the link to Cipher_Suites was lost, and later the table became outdated, with the tool to help gather the cipher lists from source not able to automate the parsing anymore.

Nonetheless the page is still linked from outside, and as a part of the recommendations should be kept up-to-date, even if it means manually for now.

There are two major signs the Cipher_Suites page should not be considered abandoned:

1. After archiving the v4 specs to Security/Archive/Server Side TLS 4.0 the Cipher_Suites page indeed did become orphaned, but not moved to */Archive/* and with no deprecation warning in the page intro, so there's no indication it should be interpreted as unmaintained.
2. Unlike the archived content that is not included in this repository, the Cipher_Suites.mediawiki page is kept here in master meaning it should still be considered part of the current docs, and kept in sync with the guidelines.

This PR makes the table useful again by:

• simplifying some of the styling to be more human-friendly for manual edits (while making the output also more readable/accessible due to better contrast),
• fixing parsing errors for the OpenSSL values used in current configs,
• updating the color-coding and priority ordering to reflect the current guidelines (v5.7),
• linking the table from main page and correctly linking the configs back,
• while removing mentions of automated updates (commented out along with timestamps et al. for now) that are no longer true.
• (+ as a bonus fixes reported syntax highlighting mediawiki issue by just using <pre/> instead of <source/>…)

This is how the render looks like:

The table is also being referenced from MDN e.g. https://developer.mozilla.org/en-US/docs/Web/Security/Transport_Layer_Security via the main wiki page, so the link should be there visible, somewhere.
