GitAttributes template: add *.groupproj (plus .sql/.ps1/.md)

[omonien]

Problem

*.groupproj is not declared in the GitAttributes template, so Delphi project
groups are exempt from EOL normalization — their line endings depend on each
developer's local core.autocrlf setting rather than on the repository's rules.

A .groupproj belongs to the same toolchain as .dproj (the IDE reads and rewrites
both), so it should be normalized the same way.

Found while auditing a Delphi project against these standards:

$ git check-attr text -- Zielsteuerung_Wiet.groupproj
Zielsteuerung_Wiet.groupproj: text: unspecified     # <-- not covered

$ git check-attr text -- tests/SDETests.dproj
tests/SDETests.dproj: text: set                     # correctly covered

Change

• *.groupproj text eol=crlf — the actual fix.
• *.sql, *.ps1, *.md — also common in Delphi repositories (migration scripts,
  build scripts, documentation) and likewise unspecified until now.
• Version header 2.0 → 2.1, which brings the template in line with
  Delphi Style Guide EN.md (already at 2.1) as its own header asks for
  ("keep in sync with Style Guide headers"). Delphi GitIgnore.txt is untouched
  and still reads 2.0 — worth a separate look, but out of scope here.

Comments are in English, matching the rest of the template.

Notes

Purely additive — no existing rule is changed or removed. For existing repositories
the header's advice applies unchanged: run git add --renormalize . after updating.

Verified on a real project: after adding the line, check-attr reports
text: set eol=crlf for the group files, --renormalize reports no content change
(the blobs were already normalized), and both project groups still build green.
