Follow up to #26542 - Brave is pinned to the taskbar upon Brave launch (when brave is NOT pinned explicitly)

Description

Currently first run dialog is disabled in Nightly and Beta. But when Brave launched first time, with or without setting Brave as a default, Brave is pinned to the taskbar. In Nightly (1.48.71), sometimes, along with pinned to taskbar, Brave icon shown as white rectangle icon.

This issue is not reproducible 100% but I have seen the issue 3 to 4 times in 3 days while dog fooding the beta build (1.46.x)

Steps to Reproduce

Scenario 1: (This mostly happens in Beta)

1. Install 1.47.136
2. launch Brave
3. context menu in the taskbar shows Brave is not pinned
4. click on a new-tab

Actual results: Context menu in the taskbar shows Brave Pinned to taskbar

Scenario 2: (This mostly happens in Nightly than Beta)

1. Install 1.48.75
2. Launch Brave

Actual results: Brave icon was pinned to the taskbar upon launch without explicitly pinned to the taskbar

Scenario 3: Brave icon not shown when pinned to the taskbar

1. Install 1.47.139
2. Launch Brave

Actual results: Sometimes, Brave icon doesn’t show when it pins and instead something like white paper icon shown

Actual result:

Context menu in the taskbar shows Brave Pinned to taskbar Scenario 1: Click a new tab Brave Beta

Brave not pinned before	Brave pinned

Brave Nightly (1.48.75)

Brave not pinned before	Brave pinned

Scenario 2: Brave icon was pinned to the taskbar upon launch

beta	nightly

Scenario 3: Brave icon is not shown on the taskbar

Expected result:

Brave should not be pinned to taskbar upon or when clicked on a new tab.
Brave icon should be shown on the taskbar

@MadhaviSeelam mind CCing me on the new issue that you create re: icons being blank? I run into that issue on a daily basis when installing Nightly while running through verifications on Win 11 x64.
