Update dependencies

[enykeev]

This PR updates softer defined \ transient dependencies and is supposed to cover for a number of open dependabot PRs in one feel swoop.

Three minor issues discovered:

• Axios no longer need data to be set on a request for content-type to be populated. Instead, it now sends the value provided in the data field verbatim and breaks auth flow. Removing previous hack fixes the problem.
• fontello-update's dependency open has been defined very broadly and as >=6.0.0 and switched to ESM starting 9.0.0. We do not use ESM on this project and it isn't worth to start because of a single transient dependency.
• When adding ST2_PROTOCOL we forgot to add it to our serve task. This creates a problem when you trying to run local version of st2web against dockerized st2.

In general, I have to admit, I'm beyond impressed with how well this project held up for all this years with minimal maintenance it had. Thanks to the community for keeping it afloat.
