feat: Include individual text values for each font

[jakubkoje]

Current Situation: Currently, as reported in #106, it is not possible to include only the requested text for each individual font. The current implementation fetches the entire font data in one call, and there is no way to specify separate text values for each font using the Google API.

Proposed Solution: To enable this feature, we need to modify the font fetching process and split it into separate calls. By doing so, we can include only the requested text for each font. This adjustment will ensure that the Google API can handle separate text values for individual fonts.

I would love to someone who is more experienced with Nuxt modules to check if the downloading still works as expected.
