Two small capitalization fixes
kded: capitalize Internet in connectivity message
The HIG recommend that proper nouns like "the Internet" be capitalized. The is one case where plasma-nm does not follow this, namely in the connectivity monitor: "This device appears to be connected to a network but is unable to reach the internet."
This change modifies this string to make "the Internet" capitalized.
The description field in the json file tor the kcm currently uses mixed capitalization: "Edit your Network Connections". This is neither of the generally recommended sentence or title cases. In particular, the recommended case for subtitles or tooltips (the most likely use of this description) is sentence case, which the majority of kcms seem to use.
This change makes the json file use sentence case: "Edit your network connections"
