Protect `cli_abort()` from curly braces

[cderv]

Look at protecting cli_abort() when messages have curly braces

See

• https://github.com/r-lib/gargle/pull/298/files

and https://rlang.r-lib.org/reference/topic-condition-formatting.html#transitioning-from-abort-to-cli-abort-

[cderv]

This seems to be happening in pkgdown error somehow
https://github.com/cderv/pkgdown/actions/runs/18954515724/job/54127733993?pr=2

this is in my fork where I tried to understand https://github.com/r-lib/pkgdown/actions/runs/18882546448/job/53889363953

I don't know what is causing the problem, and especially why it happens only on CI, and not on Windows.
Possibly this CLI error is hiding another one that is trying to be printed but has {} in message.

This could happen if for example logging of quarto goes through CLI. Example:

Notice captions from the error message in metadata field

  header-includes:
    - \KOMAoption{captions}{tableheading}
