docs: replace some toml code annotation with ini for better highlighting

Here, the thickness is directly defined in the geometry file, overwriting the default value from the `timepix` model.

All planes are randomly mis-aligned at the beginning of the simulation using the alignment precision keywords:

```toml

```ini

alignment_precision_position = 1mm 1mm 100um

alignment_precision_orientation = 0.2deg 0.2deg 0.2deg

```

Detector models for radial strip detectors are implemented in the `RadialStripDetectorModel` class. A radial strip detector model is defined using four parameters for each  strip row. In addition, its `type` has to be defined as `radial_strip`.

```toml

```ini

type = "radial_strip"

number_of_strips = 1026, 1026, 1154, 1154

angular_pitch = 0.19309mrad, 0.19309mrad, 0.17169mrad, 0.17169mrad

## Usage

```toml

```ini

[DepositionCosmics]

physics_list = FTFP_BERT_LIV

number_of_particles = 2

Example configuration for a point source at a defined position around which charge carriers are deposited with a Gaussian distribution:

```toml

```ini

[DepositionPointCharge]

source_type = "point"

model = "spot"

Example configuration for a MIP-like energy deposition along a line at a fixed position, with 63 electron-hole pairs deposited per micrometer of sensor material:

```toml

```ini

[DepositionPointCharge]

source_type = "mip"

model = "fixed"

## Usage

An example for reading energy depositions from a ROOT file tree named `hitTree`, using only the first five characters of the volume name as detector identifier and meter as unit length, is the following:

```toml

```ini

[DepositionReader]

model = "root"

file_name = "g4_energy_deposits.root"
