Fix F# property syntax documentation for attribute positioning

[Copilot]

Summary

Fixes #bcf94eb4 by correcting the syntax documentation for F# properties to show the proper positioning of attributes on get and set accessors.

Problem

The F# property syntax documentation had two issues:

1. Main syntax (combined get/set with with/and keywords) didn't show that attributes can be applied individually to get and set accessors, even though the language supports this.

2. Alternative syntax (separate get and set member declarations) showed attributes in the wrong position - they were placed before the member keyword instead of before the get()/set keywords where they should actually be applied.

Changes

Updated the syntax blocks in docs/fsharp/language-reference/members/properties.md:

Main syntax - Added accessor-specific attributes:

// Before
with [accessibility-modifier] get() =
and [accessibility-modifier] set parameter =

// After  
with [ attributes-for-get ] [accessibility-modifier] get() =
and [ attributes-for-set ] [accessibility-modifier] set parameter =

Alternative syntax - Fixed attribute positioning:

// Before
[ attributes-for-get ]
[ static ] member [accessibility-modifier-for-get] [self-identifier.]PropertyName =
    get-function-body
[ attributes-for-set ]
[ static ] member [accessibility-modifier-for-set] [self-identifier.]PropertyName
with set parameter =
    set-function-body

// After
[ static ] member [accessibility-modifier-for-get] [self-identifier.]PropertyName
with [ attributes-for-get ] get() =
    get-function-body
[ static ] member [accessibility-modifier-for-set] [self-identifier.]PropertyName
with [ attributes-for-set ] set parameter =
    set-function-body

Also updated get-only and set-only alternative syntaxes for consistency.

Verification

• ✅ Changes align with F# language specifications as demonstrated in the SharpLab examples referenced in the issue
• ✅ Markdownlint validation passed with 0 errors

This section details on the original issue you should resolve

<issue_title>Syntax for properties can be improved in terms of attributes for get and set</issue_title>
<issue_description>1. Main syntax (first one) lacks [ attributes-for-get ] and [ attributes-for-set ], though it definitely supports them.
2. Alternative syntax (second one) mentions the same [ attributes-for-get ] and [ attributes-for-set ] but in wrong positions. Because attributes would be applied to property or... ehh, lost completely?
But this way everything works.
