[Share] Fix Line Endings in Abstract

[windingwind]

Description

See #162

A right-click menu option to remove the line endings in the abstract of items.
Something similar to the Abstract Cleaner plugin: https://github.com/dcartertod/zotero-plugins

Some items have abstracts that are wrongly formatted, with many line endings remaining in the abstract.
For some items, no abstract is imported at all. If I copy from Adobe Acrobat, the line endings are also copied. I still need to remove them automatically.
That functionality was available in the Abstract Cleaner plugin. But it is not compatible with Zotero 7.

// bit more tedious but preserves paragraphs

abstract = abstract.replace(/\n\n/gm,"<br>");
abstract = abstract.replace(/\n/gm," ");
abstract = abstract.replace(/<br>/gm,"\n\n");
abstract = abstract.replace(/ +/g," ");
