Follow-up to #18102

Summary of the issue:

When fixing the `GlobalCommands.script_reportCLDR" method, I forgot that you can't just mutate lists in the config, or configobj doesn't know they've changed, so the changes will not be persisted to disc.

Description of user facing changes

The toggle CLDR script will now be persisted across sessions.

Description of development approach

Make a copy of config.conf["speech"]["symbolDictionaries"], mutate it, then save it back.
Initially tried just mutating it and then setting it to itself, but this did not work. Presumably there is some check for identity somewhere, and since all empty lists are identicle, __setitem__ was not called.

Testing strategy:

1. Assign a gesture to the script
2. Read some text with emojis. Observe the result.
3. Use the gesture.
4. Read some text with emojis. Observe the result is different to that in 2.
5. Save the config. Reload the config.
6. Read some text with emojis. Observe the result is the same as 4.
7. Repeat steps 3-6.
