Bumps virtualenv from 21.5.2 to 21.7.13.

Release notes

Sourced from virtualenv's releases.

21.7.13

Bugfixes - 21.7.13

• Fix activate and activate.fish running commands embedded in the virtual environment path or in the interpreter's Tcl/Tk library paths. (#3252)

PyPI release

Full Changelog: pypa/virtualenv@21.7.12...21.7.13

21.7.12

Bugfixes - 21.7.12

• Fix activate.bat running arbitrary commands from a crafted --prompt, VIRTUALENV_PROMPT, or config file value. (#3250)
• Verify a downloaded seed wheel's sha256 against PyPI before seeding it into a virtual environment, skipped when a custom pip index is configured. (#3251)

PyPI release

Full Changelog: pypa/virtualenv@21.7.11...21.7.12

21.7.11

Bugfixes - 21.7.11

• Running activate.bat again before deactivate no longer makes deactivate leave the environment's PKG_CONFIG_PATH, TCL_LIBRARY and TK_LIBRARY behind, or lose values the user had set before the first activation - by darrenhuai. (#3245)
• Write pyvenv.cfg values on a single line, so a prompt carrying a line boundary can no longer inject configuration. --prompt, the VIRTUALENV_PROMPT environment variable and the config file all set the prompt, and pyvenv.cfg has no escape syntax, so a newline, a carriage return, or any other boundary str.splitlines recognizes, such as U+2028, started a new configuration line. Reading the file back picked up those lines as keys, and since the last value for a key wins, they replaced anything written earlier, including home. (#3247)

Improved Documentation - 21.7.11

• Document the policy for AI-assisted contributions and the licensing rules for dependencies. (#3239)

Misc - 21.7.11

• #3238, #3240, #3241, #3242, #3243, #3244, #3246

Summary by cubic

Updates virtualenv to 21.7.13 in the lockfile, along with its transitive dependency python-discovery (1.4.3 → 1.6.4, which also drops its platformdirs dependency). The bump includes a set of security fixes from upstream: command-injection fixes in the activate scripts and prompt handling, sha256 verification of downloaded seed wheels, and protection against newline injection into pyvenv.cfg.

^{Written for commit 450e8cf. Summary will update on new commits.}

Code Review Roast 🔥

Verdict: No Issues Found | Recommendation: Merge

Oh wait, this PR is actually clean. I need to sit down. I had my flamethrower warmed up and everything.

📊 Overall: Like finding a unicorn in production — I didn't think clean lockfile bumps existed anymore, but here we are.
