[i18n] Fix broken i18n messages

[Bamieh]

Summary

We have recently upgraded the i18n packages which has some breaking changes.
The tooling upgrade to ensure that no malformed strings are in the codebase is still in progress.
The new code for the i18n_check is ready and I used it against main to detect all i18n issues we currently have in the codebase.

These are the resulting fixes we need to have in place.
I am doing this before the i18n tools are merged into main to give the core team the time to merge the PR without rushing into the code review. Additionally this ensures that the next serverless release does not contain any malformed strings.

Please filter code by team and check the changes.
The changes are:

1. Update the message id (removing duplicate ids)
2. Add ignoreTag: true where there is xml like tags that are not HTML.
3. Add other case to plural and select ICU
4. Escaped variables that needs to be unescaped

Canvas Sharable Runtime

The Canvas "shareable runtime" is an bundle produced to enable running Canvas workpads outside of Kibana. This bundle is included in third-party webpages that embed canvas and therefor should be as slim as possible.

Just one question; maybe I set it up wrong though

[lukeelmers]

We are making an exception and force-merging this as @Bamieh previously communicated:

• we've passed the TTL for review
• these are small, low-risk changes
• it is critical to get these fixed on main quickly so we don't have missing translations
