visualstar fails to properly escape search string

[zaneduffield]

Describe the bug
When using the visualstar feature on a selection containing multiple forward slashes, only the first slash is escaped in the regex used for the search.

To Reproduce

1. Paste the following text into a file

   //a
   //a
   

2. Select //a in visual mode
3. Press * (with vim.visualstar enabled in settings)
4. Observe no matches (the regex used is \//a)

Expected behavior
The regex used for the search should be \/\/a

Environment (please complete the following information):

• Extension (VsCodeVim) version: 1.27.3
• VSCode version: 1.90.2
• OS: Windows 10

I think the problem is here

Vim/src/actions/commands/search.ts

Line 102 in 2ec951a

const escapedNeedle = escapeRegExp(needle).replace('/', '\\/');

It should be replaceAll.
