Consistency needed CLI/WEB: "code cell" or "code chunk"?

Discussed in https://github.com/quarto-dev/quarto-cli/discussions/6151

Quarto documentation refers to both "code chunks" and "code cells". Quarto internals generally refer to code cells. It would be good if we could settle on a term and use it, but this might be impossible. I still wanted to record this discussion here, in case others have thoughts and want to chime in.

Some points to keep in mind:

• R Markdown and knitr refer to them as "chunks"
• Jupyter refers to them as "cells" (https://jupyterbook.org/)
• Pluto.jl also refers to them as "cells" (https://plutojl.org/)

Few statistics:

• In https://github.com/quarto-dev/quarto-web:
  • "code chunk" is used 94 times in 36 files.
  • "code cell" is used 269 times in 90 files.
• In https://github.com/quarto-dev/quarto-cli:
  • "code chunk" is used 61 times in 18 files.
  • "code cell" is used 138 times in 41 files.

Start by reviewing the terminology discussion in issue #6220 and the reported occurrences in the quarto-web and quarto-cli repositories. Establish whether one term can be selected across the documentation and internals, then update the affected references consistently and verify that no relevant usage was missed.
