ipynbdiff: strip ANSI color codes in output cells (stream and text outputs) and add tests
This merge request strips ANSI color codes from Jupyter Notebook output cells in the ipynbdiff gem, for both stream and text outputs. Previously, outputs contained ANSI escape sequences (e.g., \e[31mError in red\e[0m) which made diffs harder to read. Now outputs are plain text, improving readability.

Changes Made
- Updated
IpynbDiff.transformto remove ANSI escape codes from outputs. - Added regression tests for notebooks containing ANSI codes (
ansi_stream_text/input.ipynbandansi_execute_text/input.ipynb).
Validation Steps / Local Setup
-
Run transformation commands on test notebooks:
BUNDLE_GEMFILE=gems/ipynbdiff/Gemfile bundle exec ruby -e 'require "ipynb_diff"; f=File.read("gems/ipynbdiff/spec/testdata/ansi_stream_text/input.ipynb"); puts IpynbDiff.transform(f, include_frontmatter: false).inspect' BUNDLE_GEMFILE=gems/ipynbdiff/Gemfile bundle exec ruby -e 'require "ipynb_diff"; f=File.read("gems/ipynbdiff/spec/testdata/ansi_execute_text/input.ipynb"); puts IpynbDiff.transform(f, include_frontmatter: false).inspect' -
Confirm that the output no longer contains ANSI escape codes.
