fix: update gzip types and remove IE6 workaround in nginx config

[lbajsarowicz]

Description

Expand the gzip_types list with missing compressible content types and remove the obsolete gzip_disable "msie6" directive from nginx.conf.sample.

Changes

1. Add missing gzip types

Add three compressible content types that are commonly served by Magento but not currently compressed:

Type	Purpose
application/manifest+json	PWA web app manifest files
application/vnd.ms-fontobject	EOT font files
font/opentype	OpenType (OTF) font files

Note: WOFF and WOFF2 fonts are already internally compressed and should not be gzip-compressed (double compression increases size).

2. Remove gzip_disable "msie6"

This directive disabled gzip for Internet Explorer 6, which had a broken gzip implementation. IE6 was released in 2001 and has had effectively zero market share for over a decade. The directive is dead weight.
