Mentions: add option to allow mentions inside text

[EvgenyOrekhov]

We have a need to allow mentions inside other text.

For example, here you can see there is no whitespace before or after a mention:

But currently mention combobox can be triggered only after a whitespace:

plate/packages/nodes/mention/src/withMention.ts

Line 110 in 1ebc920

// Make sure a mention input is created at the beginning of line or after a whitespace

As a workaround, you can add a whitespace, then add a mention, and then remove the whitespace, but that is not very user-friendly.

It would be great if there was an option to allow triggering the combobox without preceding it with a whitespace.

Hi, did you ever figure this out? I tried a variety of things playing with the search pattern and trigger but never quite made it work.

Feel free to make a PR with the necessary changes to the plugin options to make this possible
