    Set-AzContext -Subscription $subscriptionId
    #Select-AzureRmSubscription -SubscriptionName $subscriptionId

    $resourcesgroups = Get-AzResourceGroup

    foreach($resourcesgroup in $resourcesgroups){

    Write-Host 'resourcegroup :' $resourcesgroup
   
    $resources = Get-AzResource -ResourceGroupName $resourcesgroup.ResourceGroupName
       #$azure_resources = Get-AzResource 


    foreach($resource in $resources){

    Write-Host $resource
{
    #Fetching Tags
    $Tags = $resource.Tags
    
    #Checkign if tags is null or have value
    if($Tags -ne $null)
    {
        foreach($Tag in $Tags)
        {
            $TagsAsString += $Tag.Name + ":" + $Tag.Value + ";"
        }

As there is no $tag.Name and $Tag.Value , Your code doesn't store any values. The output you are looking are stored as $tags.keys and $tags.values. So, to collect them you will have to use for loop again . I tested the same by replacing the for each loop for the resources with the below script:

$TagsAsString=@() 
$tagkeys =@() 
$TagValues =@() 
 $resources = Get-AzResource -ResourceGroupName <resourcegroupname>
 foreach($resource in $resources){
       Write-host ("ResourceName :")$resource.Name
       if($resource.Tags -ne $null){ 
          foreach($Tag in $resource.Tags){
             foreach($key in $Tag.keys){
               $tagkeys += $key 
             }
             foreach($value in $Tag.values){
               $TagValues += $value
             }   
          }
       }
       else{
          Write-Host ("No Tags")
       }
}
for($i = 0; $i -lt $tagkeys.Length; $i++) {
    $TagsAsString=( '{0} : {1}' -f $tagkeys[$i], $tagvalues[$i] )
    Write-Host $TagsAsString 
}

Output:
