fix(ivy): i18n - trim whitespace when parsing metadata (#34154)

Browse Source 
It is possible for HTML formatters to add whitespace
around the content of `i18n` attribute values. This can
make the meaning and custom ids brittle to simple
whitespace formatting.

This commit ensures that the metadata string extracted
from HTML `i18n` attributes is trimmed before being parsed
into meaning, description and custom id.
