Set buffer for scanner to 25MB

[dex4er]

This pull request increases the buffer size for reading output from Terraform commands in several functions, which helps handle larger outputs without running into buffer overflows or truncation issues.

Buffer size increases for reading command output:

• In terraformWithFilter (run/terraform_with_filter.go), the buffer size for bufio.NewReader is increased to 25MB to support larger outputs.
• In terraformWithProgress (run/terraform_with_progress.go), the buffer size for bufio.NewReader is also increased to 25MB.
• In terraformWithoutColors (run/terraform_without_colors.go), the maximum token size for bufio.Scanner is set to 25MB, allowing it to process much larger lines of output.
