Remove @typescript-eslint/lines-between-class-members

[monfera]

Add the required rule prefix @typescript-eslint/ before the rule name for it to actually have the intended effect.

Let's deactivate @typescript-eslint/lines-between-class-members (Expected blank line between class members) which afaict was added as part of a large set of rules and wasn't discussed specifically.

Very frequently, class members have a number of properties. They generally take up a single line. Forcing developers to add a line, automatically or not, yields objectionable, verbose code. It adds separation and heft where it often shouldn't. While beauty is in the eye of the beholder. as it's a subjective matter, let's retain the freedom - anyone can still add a line manually, but if the rule is active, it's impossible not to have a filler line.

Also, this is not a proposal to prohibit line drops.

For what it's worth, I also don't think it'd be good to enforce a line drop between adjacent top-level definitions in a file. For example, it'd enforce short constant assignments and maybe imports to be separated by a line drop
