Fix: sourcemap issue

[gabrielstellini]

Problem Description:

In the context of a Svelte project, the library produced a warning as demonstrated below:

Proposed Changes:

• The source code has been incorporated into the published bundle to resolve the aforementioned warning.
• Updates have been made to the .gitignore file to prevent unintentional publication of IDE-specific files and .npmrc.

Verification:

The changes were tested by:

• running npm pack followed by extraction of the resultant tarball into the node_modules directory of the respective Svelte project.
• running npm publish --dry-run; verifying the files for accuracy.

@NishuGoel Would it be possible to release a new version with this change on npm?

@NishuGoel I believe there's an issue in the github action configuration. It was marked as successful, even though it failed to publish https://github.com/NishuGoel/svelte-i18next/actions/runs/6571220786/job/17849970826
