Bug 41603: Automate update response preparation for legacy-only builds.

    static-update-component cdn.torproject.org && static-update-component dist.torproject.org

    ```

- [ ] **(Optional)** Generate and deploy new update responses

  - **NOTE**: This is only required if there will be no corresponding 14.0 release (i.e. this is an emergency legacy-only 13.5 release). Normally, legacy update responses are generated and deployed as part of the 14.0 release.

  - **NOTE**: This is only required if there will be no corresponding 15.0 release (i.e. this is an emergency legacy-only 13.5 release). Normally, legacy update responses are generated and deployed as part of the 15.0 release.

  - **⚠️ WARNING**: This is a little bit off the beaten track, ping boklm or morgan if you have any doubts

  - From the `maint-14.5` branch:

  - From the `maint-15.0` branch:

    - [ ] Update `rbm.conf`

      - [ ] `var/torbrowser_legacy_version`: update to `${TOR_BROWSER_VERSION}`

        - **NOTE** this is the browser version for the legacy branch, not the 14.0 branch

        - **NOTE** this is the browser version for the legacy branch, not this stable branch we've switched to

      - [ ] `var/torbrowser_legacy_platform_version`: update to `${ESR_VERSION}`

        - **NOTE** this is ESR version for the legacy branch, not the 14.0 branch

    - [ ] Generate update responses:

        - **NOTE** this is ESR version for the legacy branch, not this stable branch we've switched to

    - [ ] Generate update responses and commit them to tor-browser-update-responses.git:

      - Run:

        ```bash

        make torbrowser-update_responses-release

        ```

    - [ ] Commit new update responses to tor-browser-update-responses.git:

      - Run:

        ```bash

        updaterespdir=/path/to/tor-browser-update-responses.git

        cp torbrowser/release/update-responses/update-responses-release-${TOR_BROWSER_VERSION}.tar "$updaterespdir"

        cd "$updaterespdir"

        git pull

        rm -Rf update_3/release

        tar -C update_3 update-responses-release-${TOR_BROWSER_VERSION}.tar

        rm update-responses-release-${TOR_BROWSER_VERSION}.tar

        git add update_3/release

        git commit -m "release: new version, ${TOR_BROWSER_VERSION}"

        git push

        # print the commit hash and copy past it for the next step

        git show -s --format=%H

        cd tor-browser-build/tools/signing/ && ./deploy-legacy

        ```

  - On `staticiforme.torproject.org`, deploy new update responses:
