update utils refactor and improvements

[tarunKoyalwar]

Proposed Changes

• Tool Integrity is verified/validate when updating ( uses checksums.txt file from release if available)
• Bug fix and refactor when toolName is different than repository Name (ex: projectdiscovery/interactsh & interactsh-client)

Old implementation used GHAssetName global variable which causes problems in tool integrations ( httpx + nuclei etc ) (this has not occured yet)

• earlier v=v2.9.2 i.e version was not sent to pdtm endpoint during version check (@ehsandeep) . this issue is resolved by deprecating old callback with new one

GetVersionCheckCallback(toolName string) func() (string, error) <= deprecated
GetToolVersionCallback(toolName, version string) func() (string, error)  <= New callback

^ is not a breaking change and is deprecated properly . this will be picked up by golangci-lint gh actions downstream

• If installed tool is from dev branch ex: v2.9.1-dev it is flaged as outdated and available for update if v2.9.1 is released
• Adds support for downloading release asset (ex: nuclei-templates,fuzzing-templates etc) along with other minor improvements
