The first commit is the result of running flutter update-packages --force-upgrade and the second commit fixes two failin tests (which prevented the bot from rolling in #118412) which are caused by changes in package:mime to use text/javascript instead of application/javascript:

See dart-archive/mime#76.
See https://datatracker.ietf.org/doc/html/rfc9239.

This document defines equivalent processing requirements for the various script media types. The most widely supported media type in use is text/javascript; all others are considered historical and obsolete aliases of text/javascript.

Note: There are some additional places in the Flutter codebase that use text/javascript that I did not update in this PR because I wanted it to be the minimum required to roll the packages. If it makes sense, I can also update them (here, or in another PR).
