Fix richtext img url converting when branch name has a slash

[nyany]

The issue:

the "raw.githubusercontent" url is not replaced with the config's "output" property. Happens only with slash-containing branches like feature/onetwothree

Try to save this:

The result:

instead of url in format of $output/$relativeUrl it's https://raw.github...../$relativeUrl

Reproduction steps:

1. use a branch containing a slash (e.g. feature/foobar). Branches like develop or feature_one-123 are fine.
2. edit rich-text body field of either a collection or a single md. It must be a body field. It doesn't affect the rich-text when used in a block field.
3. add an image to the body.
4. save
5. the non-converted URL is committed.

Fix:

githubImage.ts already has encodePath function which seems to handle this problem.

commit: 3b735b0 seems to fix some bug (but doesn't say what that is). Is there a reason why it's specifically encodeURIComponent and not the encodePath function that was already there?

Shouldn't encodePath be used everywhere in githubImage.ts instead of encodeURIComponent?

There's a brand new editor in 2.0.0, with a different model for all the conversions.
