Describe what you observed.

Describe what you observed:
When I create a package named play, then rename the folder to playdos, and modify the play package declaration to an empty package declaration, gopls crashes upon pressing Ctrl+Space.

Steps to reproduce:

  1. Create a package named play: 
    ❯ ls -al
total 16
drwxr-xr-x. 1 jorge jorge   52 Jun 24 22:28 ./
drwxr-xr-x. 1 jorge jorge  418 Jun 23 07:47 ../
-rw-r--r--. 1 jorge jorge  459 Jun 19 09:50 go.mod
-rw-r--r--. 1 jorge jorge 2115 Jun 19 09:50 go.sum
-rw-r--r--. 1 jorge jorge   85 Jun 24 22:24 main.go
drwxr-xr-x. 1 jorge jorge   14 Jun 24 22:22 play/
  2. Rename the folder to playdos: 
    ❯ mv play playdos
❯ ls playdos/
play.go
  3. Modify the package declaration in play.go: 
    // Package play -.
package play
    to 
    // Package play -.
package
  4. Press Ctrl+Space and gopls crashes.

[gopls-release-branch.0.16] gopls/internal/golang/completion: fix pac…

…kage clause completion suffix

CL 585275 introduced a call to completion.Surrounding.Suffix that
exposed a latent bug in package clause completions: the completion
content was not being correctly computed as containing the cursor.

Fix the heuristics for completing at "package<whitespace>|", so that the
surrounding content is correct.

As a result of this change the 'editRegexp' from some completion tests
now no longer includes the newline, which also seems more correct.

Fixes golang/go#68169
