Bump bleach from 1.5.0 to 3.1.2

Created by: dependabot[bot]

Bumps bleach from 1.5.0 to 3.1.2.

Changelog

Sourced from bleach's changelog.

Version 3.1.2 (March 11th, 2020)

Security fixes

• bleach.clean behavior parsing embedded MathML and SVG content with RCDATA tags did not match browser behavior and could result in a mutation XSS.

  Calls to bleach.clean with strip=False and math or svg tags and one or more of the RCDATA tags script, noscript, style, noframes, iframe, noembed, or xmp in the allowed tags whitelist were vulnerable to a mutation XSS.

  This security issue was confirmed in Bleach version v3.1.1. Earlier versions are likely affected too.

  Anyone using Bleach <=v3.1.1 is encouraged to upgrade.

Version 3.1.1 (February 13th, 2020)

Security fixes

• bleach.clean behavior parsing noscript tags did not match browser behavior.

  Calls to bleach.clean allowing noscript and one or more of the raw text tags (title, textarea, script, style, noembed, noframes, iframe, and xmp) were vulnerable to a mutation XSS.

  This security issue was confirmed in Bleach versions v2.1.4, v3.0.2, and v3.1.0. Earlier versions are probably affected too.
