[typscript] change @export to @exports

[jckr]

one of the typescript templates uses a @export tag which is incorrect - the right form is @exports (see https://jsdoc.app/tags-exports). As a result, the generated code may trigger linters.

This PR corrects the syntax.

fixes #21753

PR checklist

• Read the contribution guidelines.
• Pull Request title clearly describes the work in the pull request and Pull Request description provides details about how to validate the work. Missing information here may result in delayed response from the community.
• Run the following to build the project and update samples:

  ./mvnw clean package || exit
  ./bin/generate-samples.sh ./bin/configs/*.yaml || exit
  ./bin/utils/export_docs_generators.sh || exit
  

  (For Windows users, please run the script in WSL)
  Commit all changed files.
  This is important, as CI jobs will verify all generator outputs of your HEAD commit as it would merge with master.
  These must match the expectations made by your contribution.
  You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example ./bin/generate-samples.sh bin/configs/java*.
  IMPORTANT: Do NOT purge/delete any folders/files (e.g. tests) when regenerating the samples as manually written tests may be removed.
• File the PR against the correct branch: master (upcoming 7.x.0 minor release - breaking changes with fallbacks), 8.0.x (breaking changes without fallbacks)
• If your PR solves a reported issue, reference it using GitHub's linking syntax (e.g., having "fixes #123" present in the PR description)
• If your PR is targeting a particular programming language, @mention the technical committee members, so they are more likely to review the pull request.

thanks!

[macjohnny]

@jckr please re-generate the samples (see PR description)

[davidgamero]

im debugging the same windows test failure too (unrelated to the samples afaict)

the grade Unknown command-line option '-b'. error

[jckr]

@macjohnny I have added a commit for the samples

[macjohnny]

@jckr can you merge the most recent master? maybe that resolves the CI issues

[macjohnny]

FYI this is superseded by #21776

[macjohnny]

closing this in favor of #21776

[macjohnny]

oops, #21776 was for typescript-axios, while this one is for typescript, so reopened and waiting for merging in the latest master branch

[macjohnny]

but it raises an interesting question: should the jsdoc be removed altogether, since the information is already present in typescript?
