A previous fix for insecure temporary directory issue c49100c wasn't sufficient because it followed symlinks. Stop following symlinks, and reject if a symlink; we know it shouldn't be. Fix pytest-dev#14279. [0] https://www.openwall.com/lists/oss-security/2026/01/21/5

### Summary
Fix security vulnerabilities by bumping python dependencies.
pytest through 9.0.2 on UNIX relies on directories with the
`/tmp/pytest-of-{user}` name pattern, which allows local users to cause
a denial of service or possibly gain privileges.
[tenstorrent#14343](pytest-dev/pytest#14343): Fixed use
of insecure temporary directory (CVE-2025-71176).
Pillow did not limit the amount of GZIP-compressed data read when
decoding a FITS image, making it vulnerable to decompression bomb
attacks. A specially crafted FITS file could cause unbounded memory
consumption, leading to denial of service (OOM crash or severe
performance degradation).
Fix CVE number python-pillow/Pillow#9430
nbconvert has an Arbitrary File Read/Write via Path Traversal
nbconvert allows arbitrary file writes to locations outside the intended
output directory when processing notebooks containing crafted cell
attachment filenames. The ExtractAttachmentsPreprocessor passes
attachment filenames directly to the filesystem without sanitization,
enabling path traversal attacks. This vulnerability provides complete
control over both the destination path and file extension.
lxml: Default configuration of iterparse() and ETCompatXMLParser()
allows XXE to local files. lxml 6.1.0 changes the default to
resolve_entities='internal', thus disallowing local file access by
default. See `CVE-2026-41066`.

This is my proposed alternative to #13669 as discussed in the issue. I think we should go with the simple fix for now. I think this one should be safe to backport.
A previous fix for insecure temporary directory issue c49100c wasn't sufficient because it followed symlinks.
Stop following symlinks, and reject if a symlink; we know it shouldn't be.
Fix #14279.
