Stop escaping codeFence data-code-raw attribute data

[robertKozik]

This PR is a follow up for live markdown preview web PR as there was discovered a bug which prevent parsing when special character was inside codeFence fe. ``` one > two ```.

To fix this issue we shouldn't escape data inside codeFence data-code-raw attribute so the input and output of the parser will be the same for the react-native-live-markdown library

Fixed Issues

$ Expensify/App#27977

Tests

1. What unit/integration tests cover your change? What autoQA tests cover your change?
   There are already lots of unit tests present for covering this behaviour. All relevant ones were adjusted to new behaviour
2. What tests did you perform that validates your changed worked?
   I've checked it on example app of react-native-live-markdown library which we are using for text input inside expensify app

To test the behaviour you should use example app of the react-native-live-markdown library. To do so:

1. change the expensify-common version inside /parser directory and reinstall dependencies (npm install)
2. build parser output file (npm run build)
3. Build and open example app on desired platform (iOS/Android/Web)
4. Type in code fence with special character inside it (fe. ``` one > two ```)
5. Verify that input is parsed as codeFence properly

QA

1. What does QA need to do to validate your changes?
2. What areas to they need to test for regressions?
   There should be no regressions involved as I are only changing the behaviour of html attributed used only in react-native-live-markdown library. Any regression are possible only after new version of react-native-live-markdown library is present inside E/App

@robertKozik Is it possible to test this in NewDot now?
If not, I will approve this right away.

[robertKozik]

Yeah you could but it's a long way. As you will need to locally update the expensify-common in parser directorymreact-native-live-markdown library. Then link whole lib to the NewDot. This way you should be able to test it
